Detailed Description

template<typename float_type>
class c2_function_transformation< float_type >

a transformation of a function in and out of a coordinate space, using 2 c2_transformations

This class is a container for two axis transforms, but also provides the critical evaluate() function which converts a result in internal coordinates (with derivatives) into the external representation
