Refactoring/Cleaning/Deleting: Dealing with tests.
Sections are Containers/Rows on the same document, When scrolling down, current section title is affixed on top, Header hidden on cover, Navbar section is active when the current section is on top, When a navbar link is clicked, there is scrolling to the corresponding section, Background parallax image sections, Cover section with parallax image background.
Deleting images, some styling, and hiding nav and header with z-index.
Working parallax images and styking the active section on navbar
indexSpec E2E test, installing karma-ng-html2js-preprocessor for Unit Testing directives, and working a bit the fullBackgroundImage.
Fixing indexSpec e2e test and creating 2 unit tests for the directives: parallaxImage and content
Refactoring: There is a centralized service that observes scroll changes and triggers the action to be carried on. Drectives are listening to those actions and they just modify their DOMs. Also the check of the URL has been moved to a service. At the run block those 2 new services are called. Easier to test now the scrolljng behaviour having the code in a service.
Designing/planning the remaining unit and e2e tests
Some refactoring, and unit test for 'topnavbar' directive
Deleting unused variable  on test
topnavbar test is 'Spec'
Unit test for scrollObserverService && e2e for scrolling scenario
Merge branch 'scrollingConceptLayout' into develop
Merge branch 'develop'
