Filter material from

[bam241]

Description

This aims to implement MaterialFromFilter as described in #2719

I inspired myself from CellFromFilter. I as particule only stores history of cell they travelled through and not materials, I used visited cells to list materials seen previously any the materials.

The only cons is that distribcell might contains multiple materials so this detection would be wrong. As particule might have travelled through a distribcell but not seen the requested materials.

in Cell.h line 290-293

  //! \brief Material(s) within this cell.
  //!
  //! May be multiple materials for distribcell.
  vector<int32_t> material_;

If you have any recommandation on how to implement this better, I will be happy to comply. If there is none, I can throw an Error or a Warning, stating that some cell contains multiple material so it is not possible to accurately filter by MaterialFrom.
