Readme commit
So I guess that there is a home-made testing package now
Added getBit and test for it.
Added another set of tests for getBit
Updated the readme and usage statement.
Added karnaughMap function (will be extended later) and tests for it. Added a function to find the largest value in a 2d array.
Slightly reformatted the readme.
