Done with icons when pressed.
Comments - Refactoring - Functionality.

(In the middle of changes)

So far:

1. Class "GoogleMapsButtonLayout" created to hold the layout in a
seperate class from GoogleMapsFragment. Small edits-optimization of
code.
2. Class ToucableWrapper created to hold a layout that will handle the
touch events on the Google Maps.

Currently the code that adds GoogleMapsButtonLayout is commented and the
layout is a left red line on the map.
