+Invoke Function
++++++++++++++++
+This example shows how to define an operator which gets mouse input to
+execute a function and that this operator can be invoked or executed from
+the python api.
+
+Also notice this operator defines its own properties, these are different
+to typical class properties because blender registers them with the
+operator, to use as arguments when called, saved for operator undo/redo and
+automatically added into the user interface.
