Had a bit of spare time so tried out the policy design pattern I've been learning about, applying it to PQ converters.

Browse Source 
Some interesting results:
* Minor simplification of PQ converters and unit ctors; may not seem like much, but I think it enables possible future simplifications of a similar kind.
* CMeasurementPrefix is gone, no longer needed. Now prefixes are applied at the template stage.
* Apart from that, PQs public API is unchanged.
* Discovered that ft/s^2 conversion factor was wrong: fixed.
