David Majda 6ce97457bf Fix left recursion detection
So far, left recursion detector assumed that left recursion occurs only
when the recursive rule is at the very left-hand side of rule's
expression:

  start = start

This didn't catch cases like this:

  start = "a"? start

In general, if a rule reference can be reached without consuming any
input, it can lead to left recursion. This commit fixes the detector to
consider that.

Fixes #190.

David Majda 5ce5f7a612 Specs cleanup: Use raw node types in |generateBytecode| specs
Use raw node types instead of humanized node names in |generateBytecode|
specs. This corresponds more closely to the level the specs are written
at.

David Majda 3d637173ee Specs cleanup: Split specs into unit and API specs
Unit specs are unit tests of internal stuff. API specs are tests of the
user-visible APIs and behavior.

I think it makes sense to make this distinction because then the public
API line is more clearly visible e.g. when using the specs as
documentation.
