Storyboard

This still has some more screens to be filled : 

* View a single recipe
* Show a search screen

Difference from the UI Mockups : 
* Pantry and Saved Recipes are now in one activity in their own tabs. 
* Search will be probably re-evaluated. One idea is to have check boxes on the pantry items, when you select one (or multiple), the contextual action bar pops up to either delete, or search for only those ingredients. The other idea is to have the search in the recipe gallery, and allow user to filter by terms (e.g. 'chicken)
