This part if for a RasPy group.

Number the n inputs 0 to n-1.  Give input i the 'value' of 2**i.  Sum 
the values of the hi inputs to get an integer.  (Actually, flip the 
corresponding bits of an int that starts at 0).  Create a list jpeg of 
jpegs, so that jpeg[k] is the jpeg to display when the corresponding set 
of inputs are high.

Back to RasPy.
