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.

0a21eee3f0 Remove magic number from generated symbols enums
The symbol numbers 0 and 1 are reserved for 'error' and 'eof',
so the grammar's start symbol is always 2.

1d314d71c2 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.

b2cb78166e Give Rule a virtual destructor
Not needed at the moment because rule pointers are are always wrapped
in shared_ptrs. Still, don't want to forget this if I stopped using shared_ptrs
at some point.
