When particles are added to a container class, they are sorted into an internal computational grid of blocks. The particle_order class provides a mechanism for remembering which block particles were sorted into. The import and put routines in the container class have variants that also take a particle_order class. Each time they are called, they will store the block that the particle was sorted into, plus the position of the particle within the block. The particle_order class can used by the c_loop_order class to specifically loop over the particles that have their information stored within it.

Adds a record to the order, corresponding to the memory address of where a particle was placed into the container.
[in] | ijk | the block into which the particle was placed. |
[in] | q | the position within the block where the particle was placed. |
