2    Unit tests for specific models.
3    @since: 08/25/2009
4    @note:  The models are running also with numpy array as input.
5            Some models return limit of the function at critical point .
6            So the user should expect finite value for some critical points.
7            Only critical q=0 will be tested.
8           
9            Critical points tests that fail. the user is responsible of changing
10            the model tested or document the failure.
11           
12            Initial values for models are given as the one of Igo software.

14    @summary: Run by G. Alina 10/21/2009
15            Most of the lamellar tests are not passing. Check lamellar im
16            plementation.
17            critial points tested not passing for:
