Description: Performs Geometrical Archetypal Analysis after creating
        Grid Archetypes which are the Cartesian Product of all minimum,
        maximum variable values. Since the archetypes are fixed now, we
        have the ability to compute the convex composition coefficients
        for all our available data points much faster by using the half
        part of Principal Convex Hull Archetypal method. Additionally
        we can decide to keep as archetypes the closer to the Grid
        Archetypes ones. Finally the number of archetypes is always 2
        to the power of the dimension of our data points if we consider
        them as a vector space. Cutler, A., Breiman, L. (1994)
