This is a proposal to explicitly use the Dimenstionally Extended 9 Intersection Model (DE-9IM) semantics to succinctly, conventionally, and accurately implement some of our geometric relations.

georust doesn't have a history of formal proposals before making changes (yet!?), but this seemed like a substantial enough endeavor that soliciting input from other folks up front seemed helpful.

Usage:
# given a list of numbers, print any prefixes that overlap.
#
# e.g. [1, 2, 34, 35] has no overlaps
# e.g. [1, 2, 34, 3, 5] overlaps (3 is more general than 34)
#
# This is useful in the TZip gem, since if our prefixes
# overlap, the more specific mapping will never be used - probably
# not the intended behavior of anyone inputting a mapping.
#
# Note: this doesn't detect duplicate prefixes, since they've already
