Implement a simpler, more readable and more efficient version of the sampler leveraging the Gram structure to replace the Schur complement perspective by the geometrical one: the overall procedure is akin to a sequential Gram-Schmidt orthogonalization of the feature vectors Phi(x_1), ..., Phi(x_N)
update the documentation, tests and notebook accordingly
