37 ** This class aimes to implement FACADE APIs for simgrid. The FACADE layer sits between the CheckerSide
38 ** (Unfolding_Checker, DPOR, ...) layer and the
39 ** AppSide layer. The goal is to drill down into the entagled details in the CheckerSide layer and break down the
40 ** detailes in a way that the CheckerSide eventually
41 ** be capable to acquire the required information through the FACADE layer rather than the direct access to the AppSide.
