/**
* This library provides generic functions for string manipulation, such as
* finding and extracting substrings, and pattern matching. When indexing a
* string in Lua, the first character is at position 1 (not at 0, as in C).
* Indices are allowed to be negative and are interpreted as indexing backwards,
* from the end of the string. Thus, the last character is at position -1, and
* so on.
*
* The string library provides all its functions inside the table string. It
* also sets a metatable for strings where the __index field points to the
* string table. Therefore, you can use the string functions in object-oriented
* style. For instance, string.byte(s,i) can be written as s:byte(i).
*
* The string library assumes one-byte character encodings.
*/

* and can be negative. A value of true as a fourth, optional argument plain
* turns off the pattern matching facilities, so the function does a plain
* "find substring" operation, with no characters in pattern being considered
* magic. Note that if plain is given, then init must be given as well.

* Returns a formatted version of its variable number of arguments following

* format string follows the same rules as the ISO C function sprintf. The
* only differences are that the options/modifiers *, h, L, l, n, and p are
* not supported and that there is an extra option, q.
*
* The q option formats a string between double quotes, using escape sequences
* when necessary to ensure that it can safely be read back by the Lua
* interpreter. For instance, the call
*
* `string.format('%q', 'a string with "quotes" and \n new line')`
*
* may produce the string:
*
* `"a string with \"quotes\" and \
* new line"` Options A, a, E, e, f, G, and g all expect a number as
* argument. Options c, d, i, o, u, X, and x expect an integer. When Lua is
* compiled with a C89 compiler, options A and a (hexadecimal floats) do not
* support any modifier (flags, width, length).
*
* Option s expects a string; if its argument is not a string, it is converted
* to one following the same rules of tostring. If the option has any modifier
* (flags, width, length), the string argument should not contain embedded
* zeros.

* specified by repl, which can be a string, a table, or a function. gsub also
* returns, as its second value, the total number of matches that occurred.
* The name gsub comes from Global SUBstitution.
*
* If repl is a string, then its value is used for replacement. The character
* % works as an escape character: any sequence in repl of the form %d, with d
* between 1 and 9, stands for the value of the d-th captured substring. The
* sequence %0 stands for the whole match. The sequence %% stands for a single
* %.
*
* If repl is a table, then the table is queried for every match, using the
* first capture as the key.
*
* If repl is a function, then this function is called every time a match
* occurs, with all captured substrings passed as arguments, in order.
*
* In any case, if the pattern specifies no captures, then it behaves as if
* the whole pattern was inside a capture.
*
* If the value returned by the table query or by the function call is a
* string or a number, then it is used as the replacement string; otherwise,
* if it is false or nil, then there is no replacement (that is, the original
