A Parser for Orocos Program Scripts.
This class does the actual work. It generates a Program, by constructing the ProgramNode's. We just go over the code one single time, and construct the Program as we go. For every statement, we construct a new ProgramNode, and fill it up as we get the information we need.

| rule_t & RTT::ProgramGraphParser::bodyParser | ( | ) |
Parses a multi-line program, which you can retrieve with bodyParserResult().
You need to initialize it with initBodyParser

Initialize the bodyParser to parse and store each statement it sees.
The result is retrieved with bodyParserResult().
