Deletes all components in a MotionBuilder namespace. Slight adaptation of a script by Marcus Krautwurst: http://www.marcuskrautwurst.com/2013/04/deleting-objects-in-motionbuilder.html

DeleteNamespace.py

    in_namespace = lambda c: ('%s:' % namespace) in c.LongName
    delete_comp = lambda c: c.FBDelete()
    delete_in_namespace = lambda cs: map(delete_comp, filter(in_namespace, cs))

    scene = FBSystem().Scene
