* Traverse cells of a map in parallel. Use quick traversal, cell markers or dart markers if available !
* Use this version if you need to have acces to each functors after the traversal (to compute a sum or an average for example)
* @param map the map
* @param funcs the functors to apply (size of vector determine number of threads, and all functors must be of the same type)
* @param needMarkers set to yes if you want that each thread use different markers. Warning if set to false (default) do not use algo with thread id or markers !!
