Title:
  Performance optimization of InsertionSortCollider

Status in Yet Another Dynamic Engine:
  New

Bug description:
  Sergei Dorofeenko  (https://launchpad.net/~sergei.dorofeenko) found,
  that InsertionSortCollider is probably is a "bottle neck" in
  simulations with >10^5 number of particles even in many-threads mode.

  Сitation:
  "...I did a perfomance test for parallel mode and results in no good.

  Performance boost only about 40% from 1 thread to 4 thread for 200k
  particles... Cause is a non-parallelised InsertionSortCollider, who
  need about 80% time with 4 threads.

  Results attached."
