9da7663e99 Combine TSParser and TSStateMachine objects 
My original thought was to decouple the runtime from
the LR parser generator by making TSParser a generic
interface that LR parsers implement.

I think this was more trouble than it was worth.

3cd031af38 Add keypattern rule helper 
This way, pattern rules (e.g. golang's comment) can be easily given the
same precedence as keyword rules.

e4be585c43 Handle ubiquitous tokens at the beginning of programs 
As a final step before returning the finished parse tree, check if
there are still multiple nodes on the stack. If so, make the inner
nodes children of the top node.

such as newlines, whose characters overlap with the separator
characters, can now be correctly recognized.
