New description:
Add an `edges()` method to intervals (elements of `RIF` and `CIF`).
1. For complex intervals, return the 4 edges of the rectangular interval
as intervals.
1. For real intervals, return the endpoints.
For `CIF`, we also add an `endpoints()` method returning the 4 corners of
the interval.
In other words, if the given interval lives in some N-dimensional space,
then:
1. `edges()` returns the (N-1)-dimensional faces.
1. `endpoints()` returns the 0-dimensional faces.
