+/**
+ * Abstract class with several implementations, used for
+ * matching tracks to clusters. The rules are:
+ *   1) The input tracks are supplied as a named List from the event.
+ *   2) Matched tracks are written out to the event as a Map<Track,Cluster>
+ *   3) Unmatched tracks are written out to the event as a List<Track>
+ *   4) The output tracks MAY be altered copies of the input tracks.
+ *      For example, if two tracks enter the calorimeter in the same
+ *      cell, they may get bundled into a single track. So the user
+ *      should not re-use the input track list.
+ *   5) There should be no overlap between the matched tracks and the
+ *      unmatched tracks.
+ *   6) Implementing classes MAY write out additional output.
