model.setfeaturesandsamplespace(f, samplespace)

Creates a new matrix self.F of features f of all points in the sample space. f is a list of feature functions f_i mapping the sample space to real values. The parameter vector self.params is initialized to zero.

We also compute f(x) for each x in the sample space and store them as self.F. This uses lots of memory but is much faster.

This is only appropriate when the sample space is finite.
