Detailed Description

The representation of a basic dimension: an irreducible measure. This is intended to represent a base or supplementary dimension as specified in ASTM E380-82.

I have added money as a unit because I am a pragmatist, not because I have any great desire to implement currency conversions.

The base dimension "one" is dimensionless. Any dimensionless number will have units of 1. Supplementary dimensions should have at least one unit with an option of "one" to signify that any number with that unit can have its dimension converted to 1 when required. Base dimensions should never have units with this option.
