All voxels that are outside of the model defined by the particles will be set to zero. Voxels on the surface between the model and the background will be set of 1. The interior voxels will be assign value according to their corresponding shell ( the value increases as the voxel is farthrer away from the surface).
Reimplemented from IMP::em::SampledDensityMap.

Finds all of the voxels that are part of the surface (i.e, seperate background from scene) /param[in] shell indexes of all of the surface particles will be stored here.
