===============[ Skills & achievements in Lab 3 ]===============

NOTE: In this lab, you may lose points for crashes, regressions,
      and for not providing an APK of your app.
      See "Lost Points" below.

- Creating and interacting with GoogleMaps objects
  - Creating a GoogleMap instance and fragment
  - Placing markers on the map for the cats in view and your 
    location.
  - Controlling the visibility of markers on the map based on the
    calculated distance from your location. This distance is 
    configured in your Settings fragment.
  - Controlling the data shown on the panel on click 
    of the cat marker (the cat name and image). 
  - The distance to the selected cat from the current 
    location should be updated in real time on the panel. 
  - The panel should be blank when no cat is selected or 
    if a previously selected cat goes out of view.
  - On click, the cat marker should change its appearance. 
    You can use the provided resource files to switch between
    marker appearances.
  - Update and zoom to your location on the map in real time. 
  - Extra credit (1pt): design your own markers (different from 
    the provided resource files, be creative!)
  - Extra credit (1pt): Have a configurable setting in your 
    Settings fragment that controls how frequently (the minimum
    time interval) you receive location updates. When you request 
    updates from locationManager, you should use the min time from 
    your settings fragment.
  
- Interacting with the game server
  - Handling sign-in and sign-out (the latter by deleting local data) 
  - Retrieving profile data from server and updating it on the server 
    if edited locally. This refers to the update profile functionality.
  - Retrieving the Cat List and constructing JSON object 
     representations of its element
  - Sending and handling the response from server to the "Pat" request.
    Show a Toast indicating the error if the request fails else,
  - Navigate to the Success! activity as shown in lab3.png if the "Pat" request succeeds.
    The success activity must show "Again" and "Done" buttons. The 
  - Disable the "Pat" button for a cat that has already been patted.

- Data synchronization between local storage and the server
   - Data on the server should be synchronized with the local
       profile data. When changed locally, changes should
       be uploaded. The server does not change the data 
       on its own. 
   - Local data should be deleted on sign-out and retrieved
       from the server on the next sign-in, completely
       replacing any previous data. Via this procedure,
       it should be possible for a player to use several
       accounts for independent game play or to lend 
       the phone to another account owner without sharing
       any profile data.

Each one of these 16 items earns 2 points if done correctly, 1 point
if working but any crashes occur in the related logic in our testing,
0 if not attempted or never functional.

Additional 8 points are assigned for style (2 each, as above):
  - use of git for source control
  - meaningful commenting and indentation
  - consistent use of Java facilities (constants, private, annotations, etc.)
  - modeling of data objects sent to and receive from the server
    with appropriate Java types and objects.

Overall: 16*2 + 8 = 40 points 

Lost points for regressions and crashing: Up to 3 points can be
     subtracted if an app crashes or some of the functionality
     implemented in Lab 1 stops working (a regression). Specifically,
     1 point will be subtracted if a crash occurs under some unusual
     circumstances, 2 if it occurs sporadically, and 3 if it occurs
     reproducibly on every launch. 

     2 points will be subtracted if no APK of the app is made available. 

Extra credit: 2 extra points for working "hard" mode
      	      2 extra points for reporting of upload or download 
                  progress via Notifications, with a progress bar
                  in the Notification.
	      2 extra credit points for the items mentioned in 
                "Creating and interacting with GoogleMaps objects".
	      2 extra credit points for pre-selecting the cat 
	      	closest to your location, and display information 
	      	about that cat when the user opens the Map activity.
	      
	      PLEASE do NOT upload full-size images for your profile yet!	   

Total: 40 + 8 = 48 maximum, BUT, TAs will assign up to 4 extra points for innovative 
                                 solutions, research (e.g., of bugs), or design.
