Copied mozilla license file from czmq
Problem: Needed scripts to create project files
Solution: Copy the scripts from czmq/model
Problem: The generation of classes via zclass_c.gsl is to compicated
Solution: Strip it down to the pure basics. Just the skeleton.

Idea: If one likes the current zclass_c.gsl implementation, we
      could try to execute them on imported xml file.
      E.g. <class src="class.xml" />
      As the project.xml is concerned we should keep things simple.
Problem: No prjects.xml file to test against.
Solution: Use my project.xml I've been using for a university task.

*WARNING* This project.xml is extremly ulgy and needs a lot of love.
