/**
*  The main string-token matcher.
*  The lower case part is probably not needed.  We should really be converting 
*  The string to all uppercase/lowercase to make it case iNsEnSiTiVe.
*  What Flex will do is, For the input string, beginning from the front, Flex
*  will try to match with any of the defined tokens from below.  Flex will 
*  then match the string of longest length.  Suppose the string is: POINT ZM,
*  Flex would match both POINT Z and POINT ZM, but since POINT ZM is the longer
*  of the two tokens, FLEX will match POINT ZM.
