Added Halftone Options fragment
Created better caption length checking
Fixed Halftone Options Dialog
Added Square and Diamond convert() implementations, mostly correct.
Also have ability to rotate the grid for halftone, but not implemented yet.
Completed HalftoneOptions (circles, diamonds, rectangles)
Commenting of Image class
Commented the Halftone class file, and updated the way the rectangles are calculated and drawn
Basic Grid rotation is complete. Image i rotated 45 degrees and then halftoned back to the normal orientation.
Size of the image needs to be fixed as it is being scaled down to a smaller size
Getting user input for gird angle also needs to be added
Commented Caption and Halftone Options dialog
Refactored the Halftone rotation to now be more efficient and easier to read.
It could be improved further I believe, but that can be done later.
A rotation angle slider will need to be created and used to pass in the angle of rotation
