This document needs to discuss the examples/ and regression/ subdirectories. 

Point out how the examples subdirectory illustrates some basic module features.

Point out how the regression directory while designed to preserve
gpsim's integrity also illustrates a wide variety of features. In
addition, users may experiment with particular regression tests to see
how the simulator is supporting a particular module. Perhaps this will
make it easier for users to find new bugs! (and submit patches that
fix them!).
