The two files lifebyclock.tpa and lifebylayer.tpa (which needs to be gnu-
unzipped from the distribution) update the former life.tp example to display
teapot's color and computed style capabilities.

In both files, all of the data and helper formulas are on layer 0.

In lifebylayer.tpa, you can enter whatever live cells you like with the cell
contents "1" on layer 1, making sure all non-live cells have empty contents,
and the next 36 generations of development will be calculated on the
succeeding layers.

In lifebyclock.tpa, you can enter whatever live/non-live cells you want in the
same fashion. However, now clocking the cell will advance the life simulation
by one generation per iteration, for an arbitrary number of iterations.
