* @brief Finds the next Cell for a LocalCoords object along a trajectory
* defined by some angle (in radians from 0 to pi).
* @details The method will update the LocalCoords passed in as an argument
* to be the one at the boundary of the next Cell crossed along the
* given trajectory. It will do this by recursively building a linked
* list of LocalCoords from the LocalCoords passed in as an argument
* down to the lowest level Cell found. In the process it will set
* the local coordinates for each LocalCoords in the linked list for
* the Lattice or Universe that it is in. If the LocalCoords is
* outside the bounds of the Lattice or on the boundaries this method
* will return NULL; otherwise it will return a pointer to the Cell
* that the LocalCoords will reach next along its trajectory.
* @param coords pointer to a LocalCoords object
* @param angle the angle of the trajectory
* @param universes a map of all of the Universes passed in by the Geometry
* @return a pointer to a Cell if found, NULL if no cell found
