modified Viewer constructor to accept idiomatic options argument while still supporting backward compatible positional args. documented positional args and options arg. Remove Config function allowing all configuration to occur via Viewer options (which is the only place Config was called directly). removed several pointless get_x set_x function in place of direct property access.
