* 2.7 migration (wip)
Without specifying explicitly the Twig version, since the update of require php from 5.6 to 7.0 we are getting Twig 2.12.5 !
We don't want Twig 2 as this version changes the macro scope and causes massive changes in our code... This update will be done later in other branches.
