Add remaining pills mechanism

[teodorciuraru]

Summary: Adds a mechanism through which the users will have to keep track of their medicine in order to use the application and will also help them set reminders for when they remain out of medicine.

User Profile View Controller

A new class that, for the moment, implements only the pill taking mechanism. It allows the user to set a Reminder Time for a specific interval of not having enough pills.

Example: I want to be reminded when I lack pills for more than 4 days.

Moreover, this class is the one responsible with letting the user change his current medicine stock. The user will type in their current available pills and the stock will automatically update (and also the rest of the app's screens).

A label will be presented on the bottom, stating for how long the user still has pills. If the value is lower than the value he set a reminder to track, the label will turn red and a local notification will appear..

Use-case:

The volunteers sets their current medicine stock in the User Profile tab and can start selecting if they did or didn't take their pill from the home screen or from the calendar.

In the calendar, the user still have the possibility to change decisions made for dates in the past (change Take pill into Didn't take), without the need to posses any medicine, because decisions before the Refill Date (the last date he modified his remaining medicine stock) won't affect the current stock.

When the user changes a decision made after the refill date, she will either take her medicine back (if setting I didn't took my pill when she said she took) or the medicine stock will be decremented when confirming pill taking.

Changes

• WidgetHandler logic was modified to support this mechanism.
• A MedicineStockManager was created in order to add the logic behind tracking if the user has enough pills and when to decrement / increment stock.
• All classes now call the MedicineStockManager's addRegistry() instead of the RegistriesManager one, in order for the manager to confirm if the user can add a registry at that moment (if only he has enough pills).
• A UserProfile class was created where, for the moment, only the pill taking UI was implemented.
• Adds new Unit tests for the MedicineStockManager.
• A MedicineNotificationsHelper was added in order to add a new set of custom notifications when the user lacks enough pills (based on his reminder).
• The NotificationManager now archives the notifications persistently, in order to remove correctly when needed.

Teodor, please provide a more detailed public description of the changes you made (widget, bugfix log, etc) so that this pull request is well documented.

I would ask you to submit smaller pull requests in the future, it's easier for me, for you and for anyone curious who wants to read this pull request.

@teo029 Please fix (or discuss with me) the proposed resolutions. I will still analyse it with greater detail this evening. In short, the code looks great however, when you use tuples, please identify what is each position explicitly. You scattered (..).0 on the user tests and it is still not clear to be what represents that value which a identifier would solve. IMO Constants related with view controller should remain in the view controller since they are not used anywhere else and will only impact the view controller it self. When makes sense, use @IBInspectable on those constants. All the remaining we have been discussing.

You told me that you have a new commit that fixes some bugs, just push and the pull-request will be updated automatically.

"[!] Your Podfile has had smart quotes sanitised. To avoid issues in the future, you should not use TextEdit for editing it. If you are not using TextEdit, you should turn off smart quotes in your editor of choice."

Remove the smart quote (avoid using textedit that automatically does that).

Now that I notice, you a have this error:

2016-06-26 11:09:36.069 malaria-ios[3122:31814] *** -[NSKeyedUnarchiver initForReadingWithData:]: data is empty; did you forget to send -finishEncoding to the NSKeyedArchiver?

I will resume the testing until I the current issues are solved

The icon on iPhone 6s plus is distorted horizontally.

[bphenriques]

The icon looks great now.

I would just add:

1. Fix the NSDate extensions: NSDate() + 1.day NSDate() - 1.day
2. Remove unused variables (in unit tests)
3. Add green view behind the "1 week" and change the color of textField to green as well to conform to the general theme.
