                              toyparse.h
    Functions used in the Toy Memory Manager String Parser.

    How the parser works:
      At the root of it all, is the command table.  It contains
    a list of pointers;  each pointer points to a list of strings.
    Both the table and each list in it are NULL-terminated.    
      The strings denote valid commands or valid command forms.
    For instance, say you have the root category of 'value'.  Being
    the first thing in the command table, it would be at index 0,
    and point to a list of strings, like { "#%d","\"%s",NULL };
      %d means accept any sequence of numbers in that spot, %s means
    accept any integer values in that spot.  So both "#100" and "\"Hello"
    would be accepted as valid commands.  "#100" would be subcommand
    0, while "\"Hello" would be subcommand 1.
