This will bring up the wall info selection box that is used to set the
width and height of the wall in units. Several standard configurations
are listed as well as a custom button.

Custom brings up two additional dialog boxes for manual entry
of the wall size.
Maximum size is 15 horizontal X 15 vertical units (225 projectors).

After you have selected the wall size, the ID Type in use selector will
come up. Here you will check the appropriate box for the type of numbering system that will be used to address the individual cubes in the wall.
