Updated save/edit userVdot so it checks to see if the vdot has been changed in order to enable or disable the 'Done' button.  Added isEqual and hash to UserVdot in the process
Changed the Left navbar button on the Save/Edit User Vdot screen from 'Back' to 'Cancel'.
cleanup of code via AppCode suggestions
changed action sheet to say 'Back' instead of 'Back to Edit VDOTs' as it wasn't always 'Edit VDOTs' that we were coming from
