[Olena-patches] milena r1470: Fix queue : rename empty in is_empty and add method pop_front

URL: https://svn.lrde.epita.fr/svn/oln/trunk/milena ChangeLog: 2007-11-13 Guillaume Duhamel &lt;guillaume.duhamel(a)lrde.epita.fr&gt; Fix queue : rename empty in is_empty and add method pop_front. Rename empty in is_empty and add method pop_front, which return the front element and pop the queue. * mln/core/p_priority_queue.hh, * mln/core/p_priority_queue_fast.hh, * mln/core/p_queue.hh, * mln/core/p_queue_fast.hh: Update this modification.
