Parameters :

   curLexState : lexical state in which this error occured
   errorLine   : line number when the error occured
   errorColumn : column number when the error occured
   errorAfter  : prefix that was seen before this error occured
   curchar     : the offending character
Note: You can customize the lexical error message by modifying this method.

You can also modify the body of this method to customize your error messages.
For example, cases like LOOP_DETECTED and INVALID_LEXICAL_STATE are not
of end-users concern, so you can return something like :
    "Internal Error : Please file a bug report .... "
from this method for such cases in the release version of your parser.
