// DESCRIPTION:
// C++ implementaion of tokenizing text interpretation.  Class accepts filename
// to load or pointer to preloaded text data.  Standard tokenizing operations
// such as skip white-space, get string, get integer, get float, get token,
// and skip line are implemented.  
//
// Note: all '//', '#', and ';' are treated as comments.  Probably should
// make this behaviour toggleable.
