Device Polling Layer

[MelbourneDeveloper]

Put a layer over polling for all platforms

-The factories should hang on to a reference of the devices that they have created
-Logic for checking if the device is connected should be disconnected from the device itself (i.e. Android's CheckForDevice)
-The factories should handle disconnection and connection
-When the factory scans for devices is, if an existing device is still connected, this device should be retrieved so as to not create a new one. The question is, what to do if the handle is no longer valid... Connect and disconnect?

On platforms like Windows, polling will occur with a timer. When the timer is called, the factory should check to see if the device is still connected. If not, the device should be disposed which should call the Disconnected event.

On Android, there is no need for a timer because there is an event for when a device is connected or disconnected. This might be possible on Windows and UWP in the long run...
