%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.
