Support for implicit tokens #41
Description
In Yacc we can define implicit tokens like. From the documentation:
date : month_name day ',' year ;
The comma
,is enclosed in single quotes; this implies that the comma is to appear literally in the input.
From what I can tell, double quotes do the same thing.

We've agreed that this is expected behaviour: in grmtools, the lexer is expected to lex everything, whereas Yacc does some lexing itself. We should document this in an "differences from Yacc" section.
