/**
* Class PART_PARSER
* is a localized/hidden PART Parser. You get here through the public interface
* PART::Parse(). Advantages of private class declaration in this situation:
* 1) keeps all the recursive parsing helper functions out of the main public PART
* header file and so should speed up compilation.
* 2) Allows use of cost-less Java like inline functions, since nobody knows about
* them but this source file. Most are only used once and called from one place.
* <p>
* All the functions in this class throw PARSE_ERROR. If SWEET_LEXER throws, it
* may be an IO_ERROR, propogated from here also. The throws() statements are left off
* to keep the noise level down.
