* @file synchronized_array.hh
*
* @author David Simon Kammer <david.kammer@epfl.ch>
*
*
* @brief synchronized array: a array can be registered to another (hereafter called top) array. If an element is added to or removed from the top array, the registered array removes or adds at the same position an element. The two arrays stay therefore synchronized.
