Hi François,
The Biocaml_intervalTree module is merely a specialization of Set in the
standard library. It should be fairly easy to functorize it over a type
with a total order relation. I think you might even sed -e 's/int/float/g'
the current implementation (with a couple of additional and minor
modifications).
