2 * @file substring.h
3 * @brief a small class to get the parts of a string separated by commas
4 *
5 * This class is also identified as a Tokenizer. It splits up one long
6 * String into multiple small ones by a designated Delimiter.
7 *
8 * Substring is Advanced, and it is possible, to split a string by ','
9 * but also removing leading and trailing spaces around the comma.
10 *
11 * @example
12 * Split the String std::string st = "1345, The new empire   , is , orxonox"
13 * is splitted with:
14 * SubString(st, ',', " \n\t")
15 * into
16 * "1345", "The new empire", "is", "orxonox"
17 * As you can see, the useless spaces around ',' were removed.
