Changes

** Based on the use cases, a) design '''the flows (user/UI flow, data flow) ''' of your app and b) identify '''a list of essential features ''' that you are going to design and implement on a weekly basis. The list will be used as a checklist when we go through SCRUM exercises. It is understood that your design and the list of essential features may be refined and modified as we go through the iterations. You must submit your design of flows and the list of essential features.
