// This method is called when the deformer is created by the
// "deformer" command. You can add to the cmds in the MDagModifier
// cmd in order to hook up any additional nodes that your node needs
// to operate.
//
// In this example, we create a locator and attach its matrix attribute
// to the matrix input on the offset node. The locator is used to
// set the direction and scale of the random field.
//
// Description:
// This method is optional.
