model_mi_lattice_menu (ul_model)

	mode.i4.v = model_mi_lattice_menu(row.i4.v, column.i4.v)

	This routine displays a scrolling menu of Main Injector lattice
	breakpoints and allows the user to select a breakpoint. It
	returns the breakpoint selected or -1 if none are selected. 

	row, column 	location of the upper left corner of the menu

	This function returns status values as follows:

	-1			no lattice breakpoint selected
	otherwise		selected Main Injector lattice breakpoint

	This function requires the following include files:

	ul_model_h:model_config_h
