Allen's interval algebra #17

Closed marcosh closed 4 years ago

marcosh commented 4 years ago

I recently implemented my own version of the possible relations occurring between intervals in https://github.com/marcosh/availer/blob/master/src/Availer/Relation.hs.

As suggested by @Bodigrim on reddit, it could be interesting to add this to data-interval. Would you be interested in a PR for this?

Yes, as discussed, I think it would be nice to have this vocabulary of relations, and express existing comparison operators in its terms.
