Design goals:

• Ability to express arbitrary combinations of units (via typenum)
• Reasonably short compilation errors (using const generics)
• Units should be separate from values (like in C++'s units, unlike in dimensioned)
• let speed = 10_f32 * (m / s) support (like dimensioned)
• Storage types, prefixed unit aliases & unit categories toggled via cargo features
• Lowercase constants
• Unit conversions
• Nalgebra/glam/whatever support under feature flag
