Dave AbrahamsandGeoff Romer 07a37933c6 [executable semantics] Add Syntax driver (#362)
Slowly bringing this into line with Bison's C++ example parser
so we can use strong semantic values for symbols rather than
leaking pointers.  First step is to thread a `ParseAndLexContext` 
object through the whole syntactic analysis state, like the 
example has.  In the example, it's called `driver`.
