Intersection is empty when it should not be

[skatenerd]

If we call:
MultiRange.new([10..10]) & MultiRange.new([10..20])

We should get a nonempty range. But I am seeing an empty range instead. Interestingly, the behavior is not commutative. If I flip the two arguments, I get a nonempty range.

I wonder if the fix is as simple as this?

Kinda unfortunate that the bug lives in an unmaintained repo

We could also just, internally, convert the query from 10..10 to 10, the search function is happier with this and gives the right answer, since it falls back to point_search

Thanks for the report. I submitted an issue to fast_interval_tree: greensync/interval-tree#17
And add a workaround for the issue in #33
