// Notes: CiMedia is a class which will handle multiple images and interface
//		  to allow the user to perform transformations on each one.
//
// Required Headers:
// 1) Bitmap.h -- Required for the bitmap file format structures.
// 2) Image.h -- Contains all common image definitions & formats that are
//				 shared amongst the several image format.
