Concepts
concept	mundy::ValidScalarType
	Concept satisfied by any type that is a mathematical scalar. It is a single value closed under +, -, *, /, unary - and constructible from a numeric literal.

Detailed Description

A pure traits header: it describes a scalar type and performs no arithmetic. A custom scalar (e.g. an autodiff dual) becomes usable across MundyMath by satisfying ValidScalarType and specializing NumTraits<T> with the member set shown in GenericNumTraits.
