Redesign OPENTABLE.com table management app.

I redesigned the open table tablet app as I found several issues when I go through it.
1. In an older version they are counting the number of people visit the hotel. I change it to the number of groups of people visit the hotel so it gets easy for the manager to arrange the table for a particular group.
2. Add table button is the topmost priority of the app which is not there in an older version.
3. Change some icons so they can clear the function to the user.
4. Change the several colors so that the user easily differentiate between the activity happening in the app.
