pez: colored SUCCESS/FAILURE indicator
pez: colored SUCCESS/FAILURE indicator

pez is a new bash function that can be prepended to existing functions
or commands to clearly show a colored exit status.

Example:
$ pez mmm frameworks/base/etc

will print all the usual output, and at the end either a green "SUCCESS"
line or a red "FAILURE" line.
