Allow to compile only-a-grammar or only-a-scanner. #9

Closed kjosib closed 5 years ago

kjosib commented 5 years ago

Presently the MacroParse compiler expects both a scanner definition and a parser definition. In small example documents, only one or the other may appear. This should result in an automaton object that simply lacks an entry for either scanner or parser, as is the case with the given definition file.

Rather than no entry, the entry is null in JSON. At the moment, it's possible to compile a file with neither, and get a very small automaton.
