When you call the 'python' mel-command, you're essentially running that
python code in the "__main__" module (the script editor window). This means
that only variables/functions defined in that __main__ module will be
available to the python call, and definitions made in the module where the
python call is made will not.
So you'll have to refer to your module where your definitions exist in order
to use them. You can do this generically like so:
cmd = "import %s; mayaString=%s.customClass(); mayaString.doit()" %
(__name__, __name__)
mm.eval('python("%s")' % cmd)
(beware of sys.path.append(...) as it will keep adding to your python path
in each cmd call and slow down your python import mechanism; use it only if
needed - i assume that since the module is actually running it is already
imported and so it probably already exists in the python path)
