inserting into a multimatch sorts them into order as they are added so you get the list of best matches imediately NB: probably quicker to add them to a vector and then sort them afterward

now go through from best to worst, adding to another sorted set only the matches that do not use tracks already used by a better matching pair already found

set of unique track pairings NB: for some reason, using the multiset is faster than using a vector, even though we are only iterating through it later

hooray!! now print out the answer, make a map etc this isn't technically needed, could just use the set of "matched" objects, but hey ho
