Notes of Coding Exercise

• I put a few comments in the code to indicate places where I knew a production app would be need make changes. This includes in the DataService.class and in parts of the conconcrete MVP parts. Accordingly, I did not make abstract classes for the MVP pattern.
• I did not use string.xml or dimen.xml or any of the DPI/SDK dependent res files, because this was just a test.
• There is very minor error handling and null checks--a production app would need to be hardened.
• I wanted to add a caching SQL layer, but ran out of time. A production app could sideeffect the caching on request.
• I used Java 1.8 so I didn't need to jump through hoops to use lambdas.
• The listeners attached to the ProfileViews could be replaced with Rx wrappers.
