// Desc:   TheActionManager is a convenient place for us to wrap up all sorts of logical
//				 queries about what objects can do in the world and to other objects.  The purpose
//				 of having a central place for this logic assists us in making these logical kind
//				 of queries in the user interface and allows us to use the same code to validate
//				 commands as they come in over the network interface in order to do the
//				 real action.
