A Game Of Life

To be honest this doesn't add anything to the Game Of Life.
But it has ALL the features needed:

You can edit each cell at any point in time, you can pause, you can change the gameboard width and height, you can change the simulation speed(at some point your device will throttle).

It's written part in Java and part Kotlin.
Which to be honest is the only reason any of this was written. As a self tutorial.
