* nG Python api for Gather and IE IR reader tests * also included old IE IR reader test for Gather1 * added a blank line before Gather * style corrections * applied review comments * removed blank line * removed xfailed for Gather7 with batch_dims since CPU was moved to nGraph (...allows to fallback node execution on ngraph evaluate() method in case if optimized implementation is absent) * added new visitor tests
