Overview: This function is called by GOLMsg() function when in this
particular demo each time the valid message is received for the
objects in the demo.
Input: objMsg - translated message for the object,
pObj - pointer to the object,
pMsg - pointer to the non-translated, raw GOL message
Output: If the function returns non-zero the message will
be processed by the object directly affected by the message.
Default action on the object based on the message will be
performed.
