 * @brief Unit test mechanism (to test a set of functions)
 *  
 * This module is mainly intended to allow the tests of SimGrid
 * itself and may lack the level of genericity that you would expect
 * as a user. Only use it in external projects at your own risk (but
 * it work rather well for us). We play with the idea of migrating
 * to an external solution for our unit tests, possibly offering
 * more features, but having absolutely no dependencies is a nice
 * feature of SimGrid (and this code is sufficient to cover our
 * needs, actually, so why should we bother switching?)
 * 
 * Note that if you want to test a full binary (such as an example),
 * you want to use our integration testing mechanism, not our unit
 * testing one. Please refer to Section \ref
 * inside_cmake_addtest_integration
 * 
 * Some more information on our unit testing is available in Section @ref inside_cmake_addtest_unit.  
 * 
 * All code intended to be executed as a unit test will be extracted
 * by a script (tools/sg_unit_extract.pl), and must thus be protected
 * between preprocessor definitions, as follows. Note that
 * SIMGRID_TEST string must appear on the endif line too for the
 * script to work, and that this script does not allow to have more
 * than one suite per file. For now, but patches are naturally
 * welcome.
