! The unit tests are divided into Sanity and Exhaustive. The Sanity tests are
! always run. When the environment variable, EXHAUSTIVE, is set to ON then 
! the EXHAUSTIVE and sanity tests both run. If the EXHAUSTIVE variable is set
! to OFF, then only the sanity unit tests.
! Special strings (Non-exhaustive and exhaustive) have been
! added to allow a script to count the number and types of unit tests.
