Detailed description

Description: This class enables to compute solid - solid interactions for fpi module under the framework of soft - sphere collision model. Under this framework, multiple collisions can occurs at the same time (ie a particle can collide with 2 or more particles). The collision is spread out on multiple time steps. A slight overlap (less than the mesh grid size) occurs during the process.
