Otherwise, on big models with lots of leads/lags (like GPM7), the Lagrangian
can be so huge that the preprocessor requires an insane amount of memory.

Do not issue an error message if the dseries appearing in the recursive/static expression do have common names.

reporting: remove checks on colors that are passed to graphs/series to allow for all color combinations supported by TikZ

Fixed bug. Wrong test on the number of input arguments (because of the new input argument dataset_info in dsge_likelihood).

The tests/gsa contains two datafiles with the same basename and different extensions (.m and .mat). The new behaviour of the data interface forces the user to choose between the two candidate data files (ie it is no more possible to load a data file without specifying the extension in this case).
