Detailed Description

template<std::size_t N, std::size_t... Is>
struct Euclid::MathUtils::InterpNAdapter< N, _index_sequence< Is...> >

GridInterpolation expects the data to follow GridContainer memory layout, but originally interpn is expected to follow a numpy memory layout. We use template dirty tricks to re-use GridInterpolation, transposing the axis at creation time, and the arguments at interpolation time
