Warning
  This class is fairly new and as such has not seen a lot of use in production. Please report any issues or request for new features directly to ken.m.nosp@m.uset.nosp@m.h@dre.nosp@m.amwo.nosp@m.rks.c.nosp@m.om.

Note
  While this class can arguably be used to implement a sparse Multi-Grid solver it is currently intended as a means to efficiently compute LoD levels for applications like rendering
  Prolongation means interpolation from coarse -> fine
  Restriction means interpolation (or remapping) from fine -> coarse
