- Add first draft of SWIG interface file, and create Python
loadable module. However, please note that: - All the methods accepting a Glib::ustring should not be exported, instead they should be replaced by wrapper functions accepting PyObject*. - The same thing applies to every other method accepting a ``non built-in'' data type - Return types should probably be wrapped, too - It may be a good idea to implement wrapper methods that print out the content of a C++ object, so that a Python user can do a simple "print schedStat". This is achieved by adding a "__str__()" method to the class. See the SWIG manual for further infos about returning const char* values. git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@354 3ecf2c5c-341e-0410-92b4-d18e462d057c
