Generic filter-based decision builder using an IntVarFilteredHeuristic.
Decision builder building a solution using heuristics with local search filters to evaluate its feasibility. This is very fast but can eventually fail when the solution is restored if filters did not detect all infeasiblities. More details: Using local search filters to build a solution. The approach is pretty straight-forward: have a general assignment storing the current solution, build delta assignment representing possible extensions to the current solution and validate them with filters. The tricky bit comes from using the assignment and filter APIs in a way which avoids the lazy creation of internal hash_maps between variables and indices. when the code is mature enough.
