template<typename float_type = double>
class c2_cached_function_p< float_type >
A container into which any other c2_function can be dropped.
It allows a function to be pre-evaluated at a point, and used at multiple places in an expression efficiently. If it is re-evaluated at the previous point, it returns the remembered values; otherwise, it re-evauates the function at the new point.
