Refactor algorithm to not regenerate the mesh on each update #52

Currently, the RequestData step of the algorithm completely regenerates the mesh. We should change this so that the mesh is generated once up-front, then only the data values update on the RequestData step

The performance gain from this might be marginal for rectilinear since the XYZ arrays are directly shared... only references are regenerated
