Detailed Description

All types are intended as utility type for the user options and not as a variable type for the configuration structs. They should only be used where a single option can not be represented by an existing primitive types.

They also must be distinct types and can not just be typedefs; otherwise we can not define the required operator{<<,>>} overloads in this namespace.
