  * In Command pattern actions are objects that can be executed and undone.

  * Four terms always associated with the command pattern are command, receiver, invoker and client. A command 
- * object (spell) knows about receiver (target) and invokes a method of the receiver. Values for parameters of 
+ * object (spell) knows about the receiver (target) and invokes a method of the receiver. Values for parameters of 
  * the receiver method are stored in the command. The receiver then does the work. An invoker object (wizard) 
  * knows how to execute a command, and optionally does bookkeeping about the command execution. The invoker 
  * does not know anything about a concrete command, it knows only about command interface. Both an invoker object 
  * and several command objects are held by a client object (app). The client decides which commands to execute at 
  * which points. To execute a command, it passes the command object to the invoker object.

  * In other words, in this example the wizard casts spells on the goblin. The wizard keeps track of the previous
  * spells cast, so it is easy to undo them. In addition, the wizard keeps track of the spells undone, so they
  * can be redone.
