Feature: Power

[bretthysuik]

Power has a very wide range of usable values (examples) so I'm not sure where exactly we'd want to draw the line.

There's also a tolerance issue that came up in the femtowatts unit tests: using double to store femtowatts leads to rounding/representation issues.

protected override double FemtowattsTolerance
{
    get { return 0.15; } // Need to use 0.15 instead of the standard 1e-5
}

I was thinking about this previously and I think decimal might be a better backing datatype because it can exactly represent powers of 10 because it's a decimal floating point type (double is binary floating point). It would make sense to use it since we're mainly concerned with SI units which are powers of 10, however it's a major breaking change and decimal is less efficient for calculations...

In case you haven't noticed there is already support for double, long and decimal backing types. See Information unit where I had similar issues for exabytes etc. Would that work?

[bretthysuik]

Ah, I never noticed the "BaseType" attribute in the json files. That should work for power.

Is there anything else in the pull request that needs to be addressed?

No looks good. Thanks.
