2020-02-21Operator composition (#493)Edoardo Pasca
* CompositionOperator and some refactoring * Added SumOperator and CompositionOperator added domain_geometry and optional range_geometry as parameter of Operator. These are saved in _domain_geometry and _range_geometry. Updated all operator and tests to take notice of this change. * fighting with Composition * fix direct and adjoint for CompositeOperator * fix composition Operator * remove target OUTPUT to trigger build * added unit tests * add test for ZeroOperator * fixes * add numba * removed hard coded path * removed comments * fix direct/adjoint with out parameter * removed __rmul__ * use calculate_norm inherited from LinearOperator * removed hard coded version tag * removed cached string version * use add_custom_target instead add_custom_command
