PythonProcessDesc::PythonProcessDesc

(

std::string const &

config

)

This constructor will parse the given file or string and create two objects in python-land: a PythonProcessDesc named 'processDesc' a PythonParameterSet named 'processPSet' It decides whether it's a file or string by seeing if it ends in '.py'
