Create a new multibody list (and new multibodies therein) comprised of clusters of particles that remain neighbors after a specified time spacing. Generates a distinct multibody_list for each time block. Syntax is as follows.
persistent_neighbors <time spacing at which to perform analysis> <name of neighbor list to use> <name of new multibody list and new trajectory list to create> <"centroid" or "COM">
This should be followed by a trajectory_list containing the particles to be analyzed.
