Extract index sets from particle handlers

Extract an IndexSet with global dimensions equal to
`n_comps*particles.get_next_free_particle_index()`, containing for each
particle index, a set of `n_comps*` consecutive indices associated to
the particles that are locally owned.

The indices associated to a particle with global index `n` will be the
half open range `[n_comps*n`, n_comps*(n+1))`.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
