0.2-6
   - fixed one buglet
   - fixed one incompatibility on rgamma with the latest R-devel version in the example.
0.2-5
   - eliminated the double computation (before and after the choice of K) of the first part of the classification (on which K is
	chosen) and modified part of the code accordingly.
   - added a control on the dimension of matrice.indici3 and index.matrix.
   - added the slot Dependence to the output. It contains information on the fitted copula model.
