Detailed Description

This filter extracts a contour SurfaceMesh from an image given an isovalue. Users should prefer imstkFlyingEdges over this unless sparse/local processing is needed.

One can provide this filter with a list of voxels that were modified in the image and it will locally update it such that little processing is done

It works in chunks, so a set of SurfaceMesh's are the output. One can provide the filter with the number of divisions on each axes to split up the image
