Detailed Description

template<unsigned int dim, typename T, unsigned int sh_byte, typename CellBase = CellList<dim,T,Mem_fast<>,shift<dim, T>>>
class CellListM< dim, T, sh_byte, CellBase >

Class for Multi-Phase cell-list.

This class implement a Multi-Phase cell list. In practice this Cell list can contain the particles from multiple vector distributed. By default this cell list is based on Cell list fast with shifting
