Add animation for transition from log in view to home view. Add unit tests.

- Adding transitionFromTheLoginViewControllerToTheHomeViewController
with animation.
- Adding unit tests (tests need some debugging to see why they don't
run yet).
- Remove log statements.
Adding reveal/hide functionality for the HomeView.

- Adding button on the HomeView to reveal and hide this view. When it's
revealed you can see the settings, otherwise it animates back to origin
0 and you don't see the settings.
Remove not needed files and adding .gitignore

- Removed un-needed files using command line:
git rm --cached
ContainerView.xcodeproj/xcuserdata/andreea.xcuserdatad/xcdebugger/Breakp
oints.xcbkptlist
- Adding .gitignore file
Adding the .gitignore

It did not go through last time.
