Field algbera constants as parametric types
When using the base Julia language it is frequently necessary to use Float64 or Int64 numbers as compile time constants for generating code.
FieldConstants implements a parametric type similar to Val called Constant which satisfies the mathematical field axioms.
Used in UnitSystems.jl, FieldAlgebra.jl, Similitude.jl, and MeasureSystems.jl.
