> The microsphere interpolation implemented in {{o.a.c.m.analysis.interpolation.MicrosphereInterpolator}} and its supporting class
> {{o.a.c.m.analysis.interpolation.MicrosphereInterpolatingFunction}}
> is not flexible enough for some uses.
> For example it does not allow to share a microsphere between interpolating function instances (and it always generates it from randomly generated normals).
> Also the extrapolation feature cannot be controlled, leading to sometimes unwanted artefacts.
