Intentions for mixed mode dimensions #32
Description
Following on from #31 when I got into the code, I realised _interpolate! is not generalised for mixed dimensions, but assumes all dimensions have the same interpolation kind.
So my question is: is the plan to allow arbitrary mixed interpolation dimensions?
This could be done by having one _interpolate! function and moving specialisation to dimension specific methods called in the ntuple closure. Any dimension specific setup code would need its own dispatch as well.
