command pattern is a behavioral design pattern in which an object is used to encapsulate 
all information needed to perform an action or trigger an event at a later time
Uses:
1. Macro recording: f all user actions are represented by command objects, a program can record a 
sequence of actions simply by keeping a list of the command objects as they are executed.
2. Undo
3. GUI buttons and menu items
4. Parallel processing
5. Transactional behavior ";
