To orient the last layer we'll first join all the edge cubies to reduce the OLL stage to the 3x3 equivalent which we'll then solve using the standard algorithms.
This step is a little more tedious because the algorithms still need some ironing out. For now though, we're going to use a set of algorithms derived from the 3x3 cross OLLs to join the edge cubies up. Once you have all edges built just do standard OLL and move on to step 5.
