Detailed Description

template<typename T>
struct NumTypeHelper< T >

Basic Helper functions for numeric NDB types.

As another design option, these helper functions could be defined as individual function templates, which'd allow for implicit function resolution based on the parameter type but, on the other hand, required distinct value types for all data (i.e., an Int24 value type).
