Description

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.
