Adds UnitTest++: 1.4 - minimal c++ unit test platform

UnitTest++ is a lightweight unit testing framework
for C++.

It was designed to do test-driven development on a
wide variety of platforms. Simplicity,
portability, speed, and small footprint are all
very important aspects of UnitTest++.

This commit adds the formula for the simple
install. The process is just to run the makefile
and copy the headers and libraries to the correct
place.
