Start writing unittests with the desired API / semantics.
Ignore pyc files.
Add a new test for constants and their field operation identities.
Fix a type error in a test.
Fix one test.
Split out different operational laws tests into separate unittests.
Fix unittests to use Dimensional constructor directly for dimensionless values.
Attempt to fix a __pow__ bug, but apparently Decimal('0') ** 0 is unimplemented.
Reorganize the tests to be more straightforward, and also include dimensionless values in all the laws tests.
Add special cases for __pow__ which (might) optimize runtime speed, and which pass tests by papering over a Dimensional bug.
Fix reference to one's inverse.
