Detailed Description

The command processor receives commands to manage and execute.

\ Commands can be later undone and redone. From the moment a command is pushed to the processor, the processor becomes the owner of the command and manages its lifecycle. \ the Command Processor has no knowledge of the concrete subclasses of Command and accesses them through the standard Command interface.
