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.

Separate functions for building parse and lex tables
...
Now, instead of adding states to the lex table as they are needed
by the parse states, we iterate over the parse states after the fact
and set up their corresponding lex states. This has the nice side
effect that the lex states are in a more readable order.
