Merge pull request #28 from tiger-swallowtails-2014/CF_global_controller_skeleton

Cf global controller skeleton, index view, and root route change to global#index.
YOLO MERGE - This merge replaces the root route from 'welcome#index' to 'global#index' - also replaces the controller, and index view to serve action. The same 4 tests should be failing because we haven't implemented the features that they are testing yet.
