Columns First Methods

Columns first is a group of methods that in some way build four columns of three pieces each, two adjacent corners and the and the edge between them, as the first steps. Columns are most often aligned top to bottom but two more directions are possible. An effective way to archive that is to solve four F2L pairs and do CLL for the remaining corners. Because there are no edges to preserve in the two slices that does not belong to the columns shorter algs can be used for CLL (call it CMSLL), some that else only works for 2x2x2 will do for this method. After the first part the rest of the edges and the centres are solved.
