Provides support for external quantity point-like types
<mp-units/framework/customization_points.h>
template<typename T>
struct quantity_point_like_traits;
The type trait should provide nested reference and origin objects, a type alias rep, and static member functions to_numerical_value(T) that returns the raw value of the the quantity being the offset of the point from the origin and from_numerical_value(rep) that returns T formed this raw value.
If the following expression is true, the specified conversion will be explicit: - explicit_import for the conversion from T to a quantity_point type, - explicit_export for the conversion from a quantity_point type to T.
Usage example can be found in mp-units/systems/si/chrono.h header file.
