Log:
Parser now parses the entire OMeta grammar. No AST generation yet.
On a 2.16 GHz C2D, in a VM, it takes approximately 0.6-0.7 seconds of CPU time
for the parser to run over the OMeta grammar. There is lots of potential for
optimisation over the current implementation (it generates hundreds of
identical immutable objects, for example), and most of these can be done
automatically.
For example, every rule that doesn't take any arguments can be memoised
trivially, so the expressions are created once in -init, then assigned to
instance variables and then just returned from the rule methods.
