stubbed out submit() and variables in RegisterCtrl
added ng-models and clear fields button in register view
submit() in RegisterCtrl successfully registers a new user
ng-model references user attributes
spec for RegisterCtrl
moved up spec variables to the top of file
added tests for localStorage and added 401 error code to mock error from server
using setItem() on localStorage instead of calling it by key in hash
added validate() on registerCtrl
tests for validate()
added stateMock module bc ui-router interferes with  when running specs. Doesn't work, so Im checking for every request in spec
LoginCtrl uses $state from ui-router instead of $location so we can use ui-router
just use $state.expectTransitionTo
added tours state
stubbed ToursCtrl
stateMock.js because ui.router interferes with $httpBackend tests
stub for tours view
stub scss file for future styling
no need for views obj in tours state
no need for ion-nav-view tag here
