Merge pull request #5888 from RosettaCommons/BYachnin/add_setters_for_sheettopology_helixkink
Add getters and setters to HelixKinkFilter and SheetTopologyFilter
These classes have very little in the way of getters and setters to access and modify member data. This makes it tricky to use natively in PyRosetta without XML parsing. This PR simply adds getters and setters to the classes. Thanks Vikram for the review.
