alcscope.icn: Program to visualize allocation as a kaleidoscopic display

This program displays kaleidoscopic images.  The controls on the
user interface are relatively intuitive -- trying them will give
a better idea of what's possible than a prose description here.

This program is based on an earlier one by Steve Wampler, which in
turn was based on a C program by Lorraine Callahan.

This version is adapted to visualize storage management.
