+Repeating animation
+-------------------
 
+To set an animation to repeat simply set the 'repeat' value to equal 'True'. This value is 'False' by defualt. Note* this
+is currently only implemented for 'sequence' animations. The following example illustrates how this can be done with a 
+sequential animation:
+
+   anim = Animation(value_of_first) + Animation(value_of_second)
+   anim.repeat = True
+   anim.start(widget)
+   
+For flow control of animations such as stopping and cancelling use the methods already in place in the animation module.
