Detailed Description

Provides the Expression parsing implementation.

Expressions in C99 basically consist of a bunch of binary operators with unary operators and other random stuff at the leaves.

In the C99 grammar, these unary operators bind tightest and are represented as the 'cast-expression' production. Everything else is either a binary operator (e.g. '/') or a ternary operator ("?:"). The unary leaves are handled by ParseCastExpression, the higher level pieces are handled by ParseBinaryExpression.
