Valgrind reports about problems with
InsertionSortCollider::handleBoundInversion. All memory leak from this
function, as seems. May be something  is wrong with creating of the
interactions  for the new particles?

Title:
  InsertionSortCollider memory leaks

Status in Yet Another Dynamic Engine:
  Confirmed

Bug description:
  If  add a particles after start a simulation, InsertionSortCollider's memory leak occurs.
  If set verletDist=0 in ISC, no memory leak.
