TupleCompiler

The TupleCompiler converts you input to a tuple at compile-time. The default node parser simply adds the "matches" as an unnamed string[].

The parser works in two phases, and generates code of the form "Tuple!(types...)(values...)". This can be assigned to an enum.

As in the ordinary compiler, the parser/generator methods should be overridden to parse nodes from your grammar.

There are two overrides per-node in the tuple generator - the type, and the value. The compileType returns a string; either single type, or a string of the form 'type,"name"', which would add the type as a named field in the tuple.

The compileValue method returns a string - the code to mixin when the value is computed.

This version of the compilerOverride template takes three string parameters:

the name of the node type, the code to mixin to generate the "type" portion of the Tuple! created to represent that node, and a code string to mixin to generate the "value" part of the tuple (ie the argument to the tuple constructor).
