/*! @brief : class Collision_Model_FT
 *
 *  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.
