DESCRIPTION

       A depth-first traversal of a feature node graph starts at the top-level feature node (or pseudo-node) and
       explores as far along each branch as possible before backtracking. Let’s assume that the feature nodes
       are stored in a list in the order of their traversal (called the “feature node list”).

       Two feature node graphs are considered to be repeated if their feature node lis t (from the depth-first
       traversal) have the same length and each feature node pai r (from both lists at the same position) is
       “similar”.

       Two feature nodes are “similar”, if they have the same sequence ID, feature type, range, strand, and
       phase.

       For such a repeated feature node graph the one with the higher score (of the top-level feature) is kept.
       If only one of the feature node graphs has a define d score, this one is kept.
