Nature of problem:
Inelastic colliding N-body simulations without mutual attractive force, such as some kind of molecular dynamics  or dynamics of planetary ringlets .
Alder and Wainwright's method  with our event-reduction mechanism.
No external field. This method is essentially applicable for the cases of central gravitational field, f = k r**-2, harmonic oscillation, f = k r, and other problems in which particle trajectories are predictable without numerical integration.
This program runs even if the number of potential events exceeds the capacity of the event-list. Typical optimul capacity is only N.
Several ten seconds for the test data (1600 particles).
