Patrick Lühne eaabeb0c55 Support exponentiation operator ... Because of a bug in the Clingo API, the exponentation operator was not properly exposed to anthem. This updates Clingo to a version with a fixed API and adds proper support for exponentation within anthem along with a matching unit test.		2018-04-10 22:29:55 +02:00
