Panzer: remove deprecated ConstBasis
Created by: rppawlo
This was moved into Itnrepid2. As part of #274 (closed), panzer is now using the Intrepid version. Just need to go in and remove the old version from panzer. Also need to look for code that differentiated the ConstBasis since the panzer version didn't support getDofCoordinates interface. The intrepid version now supports this.
