+/** An interval action is an action that takes place within a certain period of time.
+It has an start time, and a finish time. The finish time is the parameter
+duration plus the start time.
+
+These CCActionInterval actions have some interesting properties, like:
+ - They can run normally (default)
+ - They can run reversed with the reverse method
+ - They can run with the time altered with the Accelerate, AccelDeccel and Speed actions.
+
+For example, you can simulate a Ping Pong effect running the action normally and
+then running it again in Reverse mode.
+
+Example:
+ 
+        CCAction * pingPongAction = [CCSequence actions: action, [action reverse], nil];
