Neighbor search
virtual bool	areNeighbors (unsigned int i, unsigned int j) const
	Returns whether particles with indices `i` and `j` are neighbors.

virtual bool	areNeighbors (SBStructuralParticle structuralParticleI, SBStructuralParticle structuralParticleJ) const
	Returns whether structural particles `structuralParticleI` and `structuralParticleJ` are neighbors.

virtual void	getNeighbors (SBVector< SBStructuralParticle *> &neighborVector, const SBPosition3 &position, const SBQuantity::length &radius) const
	Appends to `neighborVector` all structural particles that are at a distance smaller than or equal to `radius` from the specified `position`.

virtual void	getNeighbors (SBVector< SBStructuralParticle *> &neighborVector, const SBIAPosition3 &box) const
	Appends to `neighborVector` all structural particles inside the `box`.

Event handling
void	onDynamicalEvent (SBDynamicalEvent *dynamicalEvent)

Debugging
