Finish some basic functions of the User Interface. User can add or deduct the number of items from the first page, and click submit to save the data in the local database (which Zehong’s algorithm will read and calculate the optimal path).

The second page is currently a dummy, to demo that the User Interface can jumps to the second page after clicking the submit button. The display of current & next item and the planned path will be implemented after integrating with Zehong’s algorithm part.
