Mesh slices are analogous to a refined P1-discontinuous mesh_fem, a list of nodes/simplexes on which the interpolation is very fast.

A slice is built from a mesh, by applying some slicing operations (cut the mesh with a plane, intersect with a sphere, take the boundary faces, etc..).

They are used for post-treatment (exportation of results to VTK or OpenDX, etc.)
