Summary: * Likely need to test this so bad formatting can't be added in the future, but cleaning all operators so we at least have good examples. * Formatting between our internal Facebook operator catalog and external caffe2.ai catalog are still slightly different. We'll work on this. Closes https://github.com/caffe2/caffe2/pull/1846 Reviewed By: pjh5 Differential Revision: D6848570 Pulled By: orionr fbshipit-source-id: b9bc0bfccb243d0440bd7b2406858cad8dc37e92
