Detailed Description

template<class T>
class Belle2::TrackFindingCDC::Scalar< T >

Class wrapping a scalar type (for which std::is_scalar is true).

Needed because you cannot inherit from scalar type directly in a mixin based inheritance structure. It does not support all the basic operations, but transparently unpacks if conversion to the underlying type is requested by the using context.
