Incorrect unit (lux) #66
Description
I think the definition for Lux, unit of illuminance, is possibly wrong.
Wikipedia defines it as 1 lx = 1 lm/m2 = 1 cd·sr/m2.
However, its dimensions in unitmath are { LUMINOUS_INTENSITY: 1, LENGTH: -2 }.
They should be { LUMINOUS_INTENSITY: 1, SOLID_ANGLE: 1, LENGTH: -2 }, given that the candela is the unit of luminous intensity.
