            - anonymous obligatory parameter
              - string with 5 char:s (tristate options: "0" do not show |
                                      "1" show nochk | "2" show and check)

              - string with 2 decimal digits "02"..."98" reducing probability
                to call expensive parser functions, default is 1 ie 100%

Returned: - one huge string

This module is unbreakable (when called with correct module name
and function name). Every imaginable input from the caller and
from the imported module "mtbllingvoj" will output either a useful
result or at least the string "Grava eraro".

Cxi tiu modulo estas nerompebla (kiam vokita kun gxustaj nomo de modulo
kaj nomo de funkcio). Cxiu imagebla enigo de la vokanto kaj
de la importata modulo "mtbllingvoj" eldonos aux utilan
rezulton aux almenaux signocxenon "Grava eraro".

The function of this module is governed by
the "Specification of the 2-dimensional table picking system".
- y-index markers are obligatory and
  lowercase (numbers and "-" not yet allowed) !!!FIXME!!!
- x-index markers are disallowed

Column numbering in the source table:
- numbering starts from ZERO
- "cy" does not count (it has theoretically index "-1")
- note that there is no comma between "cy" and "c0"
- "mpiktbllki" with special input value "+" returns the complete table line
  including the y-index marker "cy", this means that unless the "cy" part is
  trimmed off, index ZERO fed into "mpiksubstrind" will return both "cy"
  and "c0", thus the indexes used by "mpiksubstrind" will NOT be OFF-by-ONE

Structure of a row in the source table with 1+10 columns (soon 1+11):
- cy : y-index marker (2 or 3 digits)
- c0 : name of the language in the site language
       - EO: usually AJ lowercase, alternatively SB uppercase begin
       - ID: without "bahasa " and begins with uppercase letter
- c1 : QID (for example "Q5432") !!!FIXME!!! not yet almost now
       "Q" + 3...9 decimal digits
- c1 : name of the language in the language itself (may be rl-enclosed)
- c2 : constructed and antique status (digit "0"..."3")
- c3 : ISO 639-1:2002 2-letter code
- c4 : ISO 639-3:2007 3-letter code
- c5 : wiki access code (usually same as "cy" but may be different
       and longer, for example "zh-min-nan", up to 10 char:s),
       leave it "-" if code is same or unknown or does not exist
- c6 : wiki availability code (2 digits "0"..."2" ie "00"..."22"),
       "-" causes redish background and no info about availability
- c8 : name of ipedia article, base principle usually
       followed (there are some exceptions):
       - EO: core word usually AJ name with uppercased begin
             followed by " lingvo", no "la" article
       - ID: prefixed by "Bahasa " and core word begins with uppercase letter
- c9 : category with our site language ("eo" or "id") in other tionary
       (with category prefix, but without language prefix,
       without "]]" or other nonsense, may be rl-enclosed)
- c10 : number of pages in that category, apo:s ("16'384") are
        tolerable (this cannot be peeked automatically)
Note that "cy" and "c0" are ultimately obligatory, the remaining
ones are only desirable.

Overall structure of the generated page:
- top either fatal warning block or tiny block, both with purge link
- huge destination table (not if fatal error)
- technical summary block (without purge link) (may be omitted in some cases)
- bottom either fatal warning block or tiny block, both with purge link

Structure of a row in the destination table with 14 columns:
- d00 : - index (in brackets, not bold)
        - space
        - language access code (bold) (literally peeked from "cy"
          y-index marker in the source table)
        # adjust background for "eo" only
- d01 : - name of the language in the site language with link to the
          lemma page (name literally peeked from "c0" in the source table,
          must be available and valid, link augmented by "lfinsertultim"
          according to control string "contabpages[0]")
- d02 : - QID (for example "Q5432") !!!FIXME!!! not yet used
- d03 : - name of the language in the language itself
          (literally peeked from "c1" in the source table)
- d04 : - constructed and antique status (expanded from digit "0"..."3"
          peeked from "c2" in the source table)
        # adjust background to greenish or grey if applicable
- d05 : - "ISO 639-1:2002" 2-letter language code
          (literally peeked from "c3" in the source table)
- d06 : - "ISO 639-3:2007" 3-letter language code
          (literally peeked from "c4" in the source table)
- d07 : - link to the main lng category in own tionary if desired
        - EOL (if complaint below exists)
        - complaint about not existing if applicable
        - EOL (in any case)
        - number of pages (queried) or "??" if querying does not work
        - EOL (only if both cat:s are desired)
        - link to the "kap" category in own tionary with all words in
          the language (constructed from constant string "constrkatp"
          (category namespace prefix with ":") and "c0" augmented by
          "lfinsertultim" according to control string "contabpages[3]")
        - EOL (if complaint below exists)
        - complaint about not existing if applicable
        - EOL (in any case)
        - number of pages (queried) or "??" if querying does not work
        # adjust background to redish if the category (one of two)
          does not exist
        ! depends on variables "boolngsow" and "boolngexp" and "bookapsow"
          and "bookapexp" and includes expensive querying (2 or 4), column
          can be completely hidden if "bood07" is false

          the language (constructed from constant string "constrkatp"
          (category namespace prefix with ":") and "c0" augmented by
          "lfinsertultim" according to control string "contabpages[4]")

        # adjust background to redish if the category does not exist
        ! depends on variables "boovorsow" and "boovorexp" and
          includes expensive querying (2), column can be completely
          hidden if "bood08" is false
- d09 : - link to the appendix page (constructed from constant string
          "constrapxp" (appendix namespace prefix with ":") and "c0"
          augmented by "lfinsertultim" according to control string
          "contabpages[1]") controlled by "booapxsow"
        - EOL (only if both pages are desired)
        - link to the index page in own tionary with
          the language (constructed from constant string "constrindp"
          (index namespace prefix with ":") and "c0" augmented by
          "lfinsertultim" according to control string "contabpages[2]")
        # adjust background to redish if at least one of them does not exist
        ! depends on variables "booapxsow" and "booapxexp" and "booindsow"
          and "booindexp" and includes expensive querying (1 or 2), column
          can be completely hidden if "bood09" is false
- d10 : - quasi-external link to wikipedia in the language concerned
          (constructed from "c5" and "c6" and "cy", irrespective availability)
        - EOL (if note below exists)
        - note about bad availability if applicable
        # adjust background to redish if "c6" is not available
        # adjust background to grey according to bad availability
        ! no expensive querying here
- d11 : - quasi-external link to tionary in the language concerned
          (constructed from "c5" and "c6" and "cy", irrespective availability)
        - EOL (if note below exists)
        - note about bad availability if applicable
        # adjust background to redish if "c6" is not available
        # adjust background to grey according to bad availability
        ! no expensive querying here
        & special rule ie blocking for own site language
- d12 : - quasi-external link to the article in own ipedia about the language
          (article name constructed from "c7", or alternatively if "c7" is
          not available then it is guessed using "lfinsertultim" from "c0"
          and "contabpages[6]" and " (??)" is added)
        # adjust background to redish if "c7" is not available
        ! no expensive querying here
- d13 : - quasi-external link to EO or ID category in the tionary in the
          language concerned (peeked from "c8" in the source table)
        - EOL (if number of articles below exists)
        - number of articles (peeked from "c9" in the source table)
        # adjust background to redish if "c8" or "c9" is not available
        ! no expensive querying here
        & special rule ie blocking for own site language

Expensive querying:
There are up to 8 expensive queries (3 cat:s plus appendix plus index, one
cat costs 2 bucks ("ifexist" and "pagesincategory") per page, appendix and
index cost one buck per page) per language and thus table row. This is a big
problem in "mkomtbllin" but in "msngtbllin" it is no problem at all. The hard
limit set by wiki software is 500. The totally fired number of calls can be
reduced via parameters "boolngexp" "bookapexp" "boovorexp" "booapxexp"
"booindexp" "numproba". We even have a fraud implemented.

Error handling:
- "booerr" set to true if we fail to import the source table, or
  the argument supplied from the caller is bad, output is minimal with
  huge error "#E07 Grava eraro" then, no huge table and no
  technical summary block, fatal warning YES, "numtblper" is NOT valid
- "booearsyn" set to true if early syntax check fails (line ZERO with
  "[[eo]]" or "[[id]]" not found or not valid), output is minimal with
  huge error "#E07 Grava eraro" then, no huge table and no summary,
  fatal warning YES, "numtblper" is valid (can be ZERO or equal "numtblend")
- "boomxwerr" is a "maxwidth" violation error or line without EOL,
  checked before and after row, abort immediately, huge error
  "#E06 Linio estas tro longa", summary YES, fatal warning YES
- "boosinerr" set to true in a table row, the row is completed (risk
  for "-"), loop exited and table closed, huge error
  "#E05 Sintaksa eraro" is outside the table, summary YES, fatal warning YES
- "boosorerr" temporarily set to true and "numsorerr" incremented for
  every sorting error (not possible in line ZERO), lagom error "Sortiga
  eraro" is in the table element at column 0, do not exit
  the loop, fatal warning YES
- "numerrtru" (no bool) incremented for every truncated line in source table
  having "cy" and "c0", minimal error "Nekompleta linio" is in the table
  element at column 0, do not exit the loop, fatal warning NO
- "numerrtlo" (no bool) incremented for every too long line in source table,
  lagom error "Tro longa (ele) linio" is in the table
  element at column 0, do not exit the loop, fatal warning YES
- "numerrkec" (no bool) incremented for every minor
  error (possible in line ZERO), do not exit the loop, fatal warning NO
- "numerrkap" (no bool) incremented for every missing "kapvorto" category
  error (possible in line ZERO), do not exit the loop, fatal warning NO
- "numerrvor" (no bool) incremented for every missing "vortaro" category
  error (possible in line ZERO), do not exit the loop, fatal warning NO
- "numerrind" (no bool) incremented for every missing index page
  error (possible in line ZERO), do not exit the loop, fatal warning NO
- if "mw.title.getCurrentTitle().prefixedText" does not reveal our
  pagename (needed for purge link) then we don't whine but use a bad
  default "Special:Recent changes" instead
