provides a special type of String for tokenizing
purposes. It provides a method with the same functionality
of strtok and a method for token advancing. It was written
when strtok gave me a headache when I introduced POSIX threads
to gPS. All operations (containment, for example) are performed
on the current token, not the whole string.
