Checks 'ldk' shapes

A simple utility, used internally, mostly by Ldk methods, in some graphical functions, and notably in l2a. Returns an array of landmarks arranged as (nb.ldk) x (x; y) x (nb.shapes), when passed with either a list, a matrix or an array of coordinates. If a list is provided, checks that the number of landmarks is consistent.
