Provide Jython scripting binding and use it as the default engine when cPython is missing at runtime.
Discussion with Nick Hauser on 24/12/2009
Either Jython or Python (jepp) is acceptable, but Jython is more cross-platform and stable (jepp may crash JVM if some third party library code is called).
May consider learning some GDA Jython scripting concepts to enhance GumTree (see: http://www.opengda.org/)
Working in progress.
Jython script engine is added to GumTree.
