Update README.markdown

First change: Example 2: mySidePanelController => MySidePanelController

Convention says class names should have a capital first letter. The README makes you do a double-take because you wonder if maybe you mean you need to create an *instance* of JASidePanelController (which uses lowercase by convention) as opposed to a subclass.

Second change: Example 2, #4: views => view controllers

#4 states you should drag in more views, but you should really drag in more view controllers.

Thanks for the great lib!
