## Realsets

realsets.py is a [Sage][] module to support subsets of the real field consisting of intervals and isolated points and was developed to demonstrate set operations of the MGL Set1 module.

It is based of previous work from Interval1Sage adding integration on real sets and real intervals.

An object in this module consists of a list of disjoint open intervals plus a list of isolated points (not belonging to these intervals). Notice that Infinite is acceptable as interval bound.
