* ./hurricane/src/hurricane :

- Bug : memory leak in Query.h. When we do try a levelDown() remove the
        Instance locator that have been created (and is not valid).
    - To trace the numbers of Instances Locator add a counter inside the
        QuadTree. The code is commented but could be useful in case of
        another memory leak...
