Etape 2 sur 6743542 : parsing et tentative de mise en cache des AST des ficheir de tout le framework.
Avec dumpAST : 4m37 d'exec. Avec serializeAST : 3m30 mais tous les fichiers sont vides car json_encode n'encode pas les objets !!! git-svn-id: file:///var/svn/2012-php-weave/trunk@11 d972a294-176a-4cf9-8ea1-fcd5b0c30f5c
