/** \Class PyImageFilter
 *  \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. ;)
 *
 * This class was contributed by Charl P. Botha <cpbotha |AT| ieee.org>
