> Currently, {{MatchingFacetSetCounts}} iterates over {{FacetSetMatcher}} instances passed into it linearly. While this is fine in some cases, if we have a large amount of {{FacetSetMatcher}}'s, this can be inefficient. We should provide the option to users to enable the use of space partitioning data structures (namely R trees and KD trees) so we can potentially scan over these {{FacetSetMatcher}}'s in sub-linear time.
