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.

| rule_t & RTT::StateGraphParser::parser | ( | ) |
Returns the top-level parser for state machines.
It parses one state machine definition or one state machine instantiation.

| void RTT::StateGraphParser::storeOffset | ( | ) |
Stores the current position in the input stream (iterator received from the constructor) in order to be able to extract the statemachine's text from the input stream.
You need to call this function once before using the parser().
