Create custom transition for sub-grid position taps

[JamesLongman]

When the user taps on the sub-grid container view in the coordinate input sections the container view transitions to a fullscreen version in its own custom view so that the User will be allowed greater positional resolution.

The transition is currently a simple animation where a full screen version transforms onto the screen from bellow the view. However it would look better and be more intuitive if the container view that was touched simply expanded to a fullscreen version.

This may or may not require a custom animation
