Store edits in trees, not by splitting stack
...
This allows for multiple edits per parse, though it is not exposed through
the API yet

Handle goto actions after reductions in a more standard way
...
Rather than letting the reduced tree become the new lookahead symbol,
and re-adding it to the stack via a subsequent shift action, just
add it to the stack as part of the reduce action. This is more in
line with the way LR is described traditionally.

Remove generated parsers' dependency on the runtime library
...
Generated parsers no longer export a parser constructor function.
They now export an opaque Language object which can be set on
Documents directly. This way, the logic for constructing parsers
lives entirely in the runtime. The Languages are just structs which
have no load-time dependency on the runtime
