	Identify interacting particles.

Variables
tarch::multicore::BooleanSemaphore	swift2::kernels::internal::_multiscaleInteractionSemaphore
	If particles on multiple levels interact, we have to be very careful and ensure that multiple subcells (if mapped onto tasks) do not write to the same coarse grid particles concurrently.
