*	Move ALU test cases to external testcase file	Bobby Bingham	2017-01-08	4	-48/+76
\| \| \| \| \| \| \|	This makes is a little easier to create new ALU testcases and to quickly read and understand the existing testcases. Additionally, the test bench itself can now report when a test fails, rather than requiring inspection on the waveform (though the waveform is still available).
