 * COS_TLV: the retro cosine
 * COS_TLR: the classic reflected and light cosine

The parametrization is still an issu, it should be converted to an object where
the dimension is included so that the convertion can be done.

Cleaning the parsing code for Beckmann and retro Beckmann lobes.

They should not call the get_name function

Correction of the L2 & Linf distance with respect to the objects params
Updating the example in python

The Beckmann distribution wasn't working due to the lack of correct Jacobian for the Geometric term. I commented the Geometric term from the BRDF to get correct fit. Will need to work on that.

Adding dimension interpolation

Need to find a way to add information to Nd points.

Allowing to extract slices of data from the data2gnuplot interface

Changed the interface of the data2gnuplot.
