I have an application for which I have been considering implementing an
interval tree (i.e. A
quick look at your docs does not reveal the implementation that you are
using, but I have the impression that it's something different.

Can you comment on the complexity / efficiency of whatever you're doing
compared to a traditional interval tree? I.e. complexity for insert
and lookup, storage required, number of bytes of overhead per element
etc. To make that concrete, say I have N items and for each I store
one pointer indexed by an interval of floats. How much space is
needed, and how much time is needed to find the M items that
(partially) overlap some interval?

Sorry if this is in the docs somewhere but I couldn't find it.

Cheers, Phil.
