Data structures have been created to store setup information.
Forgot to add Setup.m and SetupStep.m to EMBRACE target
#9 and #10 : Data Structures for Solutions and Setups  added.
#9 and #10: Setup and solution steps are stored as ActionSteps. PMActivity has an array of setup steps and a PMSolution (subclass of Solution) with an array of solution steps. Setup implementation was attempted in PMViewController.
#9: Moved performSetupForActivity to webViewDidFinishLoad. Setups are now implemented on story open.
Removed mention of who added the function and inserted block comment
