/*
Description: This comparison aims to determine the running time difference
between the Boost string tokenizer and the String Toolkit
Library's string tokenizer. The comparison involves each
tokenizer accepting a set of possible delimiters and a string to
be tokenized. The provided string is tokenized and the tokens are
subsequently concatenated to each other.
Running time is measured around the tokenization loop, and
printed out along with a measure indicating the average number of
tokens parsed per second. Furthermore, the tests include a simple
comparison of integer, double to string and vice-versa conversion
routines between the standard library, BOOST and String Toolkit.
Definitions:
tks/sec : Tokens per second
nums/sec : Numbers per second
