Update KPI's and refactor software

Added new & updated existing KPIs

- add KPIs for measuring user behavior for analytics and product improvement purposes - refactored code for better maintainability

- adds a notification system where the app sends a notification if a user recently tried to find parking and a new spot just showed up near them

- Add rotatable map - Add ability to see streetview on parking pins - Add ability to see travel route from user to pin - Add ability to enter zoomed navigation mode to help navigate to pin - Add feature to allow testers to long press on the map to create a test parking pin which they can then use in order to verify functionality

- changed nearby parking notification logic to occur more infrequently

- added better metrics to track algorithm performance - fix bug during parking detection

- introduce much improved algorithm which should multiply amount of parking detected - fix minor detection bugs

- better facebook event tracking for better targeting when promoting app to users

- Algorithm tweaked for better performance

- adds much more streamlined and intuitive introduction carousel to explain the app - adds better messaging for permission prompts - adds option to allow for notification when parking is later detected - improves parking detection algorithm

- added more Facebook app event triggers for better targeting towards actual active user - addressed crash with Popup library

- included Facebook SDK

Updated parking detection algorithm from 10% daily detection rate (100 spots per day from 1000 users) to 40% detection rate (400 spots per day from 1000 users).

Removes bug caused by UI component being modified outside main thread. Have removed this modification.

1.1.5 Adds a new feature where old spots are shown as tiny red dots on the map. If fresh parking is not available, users can see which blocks have commonly had spots open up, and then check them for openings.

1.1.4 Increase search radius to 3 miles, and shows parking spots up to 60 minutes old.

1.1.3 - Changes location permission message and changes the icon.

Version 1.1.0 completely removed the manual process of users having to go to their car, connect their phone to it, and then identify their car-connection to Co-Park. Now, Co-Park cleverly picks up which connection is your vehicle. As a result, the experience is much, much more seamless. Users can download Co-Park, allow the necessary permissions, and that's it. Though user flow remains the same, this version also makes minor UI adjustments in many parts of the app for an overall better experience. Version 1.1.2 optimized the parking-locations retrieval query. The old query potentially pulled unnecessary parking spot entries, which could potentially lead to long load times for users. This version greatly optimized the query to handle some of the filtering work in the database, so that user's running apps don't get overloaded with a huge number of parking pins.
