 * This enumeration is intended to be used to help us discriminate neighbor relationships for the

 * Possible visualization behaviors could be the following: - IN ( draw a line with 1 arrow ) - OUT
 * ( draw a line with 1 arrow ) - BOTH ( draw a line with 2 arrows, or 2 lines with 1 arrow each ) -
 * UNKNOWN ( draw a line with no arrows )
 * The UNKNOWN case is what we have at the moment where we have a collection neighbors with no
 * knowledge of relationship directionality.
