stuck on navigating to different periods... HELP!
[axof: 4]
Added perameters to the state provider that will accout for classes. Added controllers for the main page views. Added common period controller. Added 2 period navigations - on when no period is selected, the other is for changing periods. Using ng-show to display appropriate content.   Still  Needed: styling, centering the period buttong and coding it to double as a title, get animations working properly, add a readme.  Period information is in the periods/periods.json file - httpService calls and chaches it. [axof: 4]
