Started work on creating a button style for this application.
Updated code to generate a collection of colours prior to assigning colours to the buttons on screen.
Activity now creates a chosen colour prior to adding any fragments to the screen layout. This colour is then added to the collection of colours to use in the actual test fragment.
Added code to display the chosen colour.
Updated to use new button style.
A utility class for the Colour enumeration.
