411: Autoconfiscate the project and automate the tests.

This is just a simple packaging, mainly to automate the tests. I know that previous Olena release/prototypes came with a much more complex equipment (w.r.t configuration and tests); but don't worry, we'll add this later. https://svn.lrde.epita.fr/svn/oln/trunk Index: ChangeLog from Roland Levillain <roland(a)lrde.epita.fr> Autoconfiscate the project and automate the tests. * configure.ac: New file. * Makefile.am, build-aux/Makefile.am, metalic/Makefile.am, * metalic/mlc/Makefile.am, metalic/tests/Makefile.am: New file.
