Detailed Description

This is not a parser in the Boost.spirit sense of the word, it's just a class used to hold the parser and semantic actions..

This class does the actual work. It generates a Finite State Graph, by constructing the State nodes. We just go over the code one single time, and construct the FSM as we go. For every statement, we construct a new GraphNode, and fill it up as we get the information we need.
