 in the kmean algorithm, it may happen that one cluster do not have any
 samples anymore, which means the cluster is "lost". For now, a warning is
 sent when this happen; this is fine when using kmeans2 directly, but can
 be a problem when used by other algorithms who may need to catch the
 error. Maybe as a parameter  ?
