tspplot() creates a plot of each top scoring pair.The figure plots
the expression for the first gene in the TSP pair versus the expression
for the second gene in the TSP pair across arrays. The user defined
groups are plotted in the colors red and blue. The score for the pair is
shown across the top of each plot. If there is more than one TSP,
hitting return will cycle from one TSP to the next.
