Base class to calculate force between SPH particles.
This is an abstract class that defines an interface that various SPH method should implement. The class owns a collision system fsi which takes care of GPU based proximity computation of the particles. It also holds a pointer to external data of SPH particles, proximity data, parameters, and numbers. Child class must implement Initialize and ForceSPH methods.

Copy sorted data into original data (real3).
This function copies the data that are sorted in the collision system, into the original data, where data is real3. The class is invasive, meaning that the sorted data will be modified (and will be equivalent to the original). Therefore, this function should be used whenever sorted data is not needed, but efficiency is preferred.
