patrick 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.

patrick c294a29cb2 Support placeholders with #external declarations 
This adds support for declaring predicates as placeholders through the
“#external” directive in the input language of clingo.

Placeholders are not subject to completion. This prevents predicates
that represent instance-specific facts from being assumed as universally
false by default negation when translating an encoding.

This stretches clingo’s usual syntax a bit to make the implementation
lightweight. In order to declare a predicate with a specific arity as a
placeholder, the following statement needs to be added to the program:

    #external <predicate name>(<arity>).

Multiple unit tests cover cases where placeholders are used or not as
well as a more complex graph coloring example.

patrickandpatrick 22238bb398 Switch to C++17 
With C++17, optionals, an experimental language feature, were moved to
the “std” namespace. This makes C++17 mandatory and drops the now
obsolete “experimental” namespace.
