14 More features, more fixes

This morning we quickly solved the issue we had left yesterday. We soon realized the problem causing some difficulty in the arrays processing was a lack of files for it to read. The features we added today were focused mainly around increasing ease of use of the program, notably error messages. Now if someone sets the array live and there are no images to process it notifies the user and makes the array offline. Overall today was very productive, we will be continuing similar work tomorrow, and also start testing some alternate configurations generated in Maya.
