// Reads in the void catalog and removes any void that could potentially
// be affected by a mock particle. It does this by computing the longest
// particle distance within each void and comparing it to the distance
// of the nearest mock particle. If the void could potentially by rotated
// to include this particle, we throw out the void.
// This is placed here instead of using the edgeAvoidance option in
// stackVoidsZero so that we can optionally filter the entire
// catalog at once before the stacking phase. This is useful
// for producing a "clean" void catalog for other purposes.
