	Purpose
		This class handles the setup and printing
		of the grid to a printer or other printing
		device.
	Details
		-This class has two printing sections,
		 setup, and printing. Setup is required
		 to figure out how many pages it will take
		 to print a range of cells from the grid.
		 Plus which cells to print on which pages.
		 Once the setup is complete a page can
		 now be printed.
		-Printing setup function: PrintInit
		-Page Printing function: PrintPage
		-The rest of the printing functons are optional
		 and are used to setup different print options.
