* \brief Command subclass that calls a Python callable object, e.g.
* a Python function.

* With this class, arbitrary Python callable objects (e.g. functions)
* can be associated with an instance to be used in AddObserver calls.
* This is analogous to itk::TclCommand, but then a tad more flexible. ;)
