Bitwise AND circuit and doctest.
Unit test for bitwise AND circuits
Changed doctest for bitwise AND circuit to be more concise (using only 1 source circuit).
Bitwise OR and XOR circuits, doctests only.
Unit tests for bitwise OR and XOR circuits
Bitwise NOT circuit and tests
Digital arbitrary circuit with doctest
Unit test for digital source circuit
Left rotate modifier and doctest.
Right rotate modifier and doctest. Tweaked doctest for left_rotate to be a little more informative.
Unit tests for rotate modifiers.
Gotta change the circuit implementation again.
Mergel circuit multi-input wiring change in.
Full adder and doctest
Full adder unit test.
Moved internal component connections for full_adder_circuit to helper function, initial implementation of ripple-carry mod adder. Better doc for full_adder_circuit.
N-bit ripple-carry mod adder passes doctest after some very painful debugging.
Unit test for ripple adder circuit. Fixed error that connected sum bit of
first half adder to next full adder (xor -> xor changed to and -> xor).
Deleted extra line in docstring for digital_source_circuit.
Merge with all circuit features.
