示例1: stringToList
/**
* Generic tokenizer.
* Splits source into tokens and tries to lexically cast them to TARGET.
* If that fails, boost::bad_lexical_cast is thrown.
* \param source the source string to be split up
* \param separator regular expression to delimit the tokens (defaults to \\s+)
* \param prefix regular expression for text to be removed from the string before it is split up
* ("^" if not given, will be added at the beginning)
* \param postfix regular expression for text to be removed from the string before it is split up
* ("$" if not given, will be added at the end)
* \returns a list of the casted tokens
