Detailed Description

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.
