/*
* It is strictly recommended to include "testlib.h" before any other include
* in your code. In this case testlib overrides compiler specific "random()".
*
* If you can't compile your code and compiler outputs something about
* ambiguous call of "random_shuffle", "rand" or "srand" it means that
* you shouldn't use them. Use "shuffle", and "rnd.next()" instead of them
* because these calls produce stable result for any C++ compiler. Read
* sample generator sources for clarification.
*
* Please read the documentation for class "random_t" and use "rnd" instance in
* generators. Probably, these sample calls will be usefull for you:
* rnd.next(); rnd.next(100); rnd.next(1, 2);
* rnd.next(3.14); rnd.next("[a-z]{1,100}").
*
* Also read about wnext() to generate off-center random distribution.
*
* See https://github.com/MikeMirzayanov/testlib/ to get latest version or bug tracker.

/*
* Very simple regex-like pattern.
* It used for two purposes: validation and generation.
*
* For example, pattern("[a-z]{1,5}").next(rnd) will return
* random string from lowercase latin letters with length
* from 1 to 5. It is easier to call rnd.next("[a-z]{1,5}")
* for the same effect.
*
* Another samples:
* "mike|john" will generate (match) "mike" or "john";
* "-?[1-9][0-9]{0,3}" will generate (match) non-zero integers from -9999 to 9999;
* "id-([ac]|b{2})" will generate (match) "id-a", "id-bb", "id-c";
* "[^0-9]*" will match sequences (empty or non-empty) without digits, you can't
* use it for generations.
*
* You can't use pattern for generation if it contains meta-symbol '*'. Also it
* is not recommended to use it for char-sets with meta-symbol '^' like [^a-z].
*
* For matching very simple greedy algorithm is used. For example, pattern
* "[0-9]?1" will not match "1", because of greedy nature of matching.
* Alternations (meta-symbols "|") are processed with brute-force algorithm, so
* do not use many alternations in one expression.
*
* If you want to use one expression many times it is better to compile it into
* a single pattern like "pattern p("[a-z]+")". Later you can use
* "p.matches(std::string s)" or "p.next(random_t& rd)" to check matching or generate
* new string by pattern.
*
* Simpler way to read token and check it for pattern matching is "inf.readToken("[a-z]+")".
