Theorem ismrcd1 26876
 Description: Any function from the subsets of a set to itself, which is extensive (satisfies mrcssid 13535), isotone (satisfies mrcss 13534), and idempotent (satisfies mrcidm 13537) has a collection of fixed points which is a Moore collection, and itself is the closure operator for that collection. This can be taken as an alternate definition for the closure operators. This is the first half, ismrcd2 26877 is the second. (Contributed by Stefan O'Rear, 1-Feb-2015.)
