CreateDiffData[sig,eig,bvec,gradients,dim]

creates a DTI datasets of dimensions dim with sig as unweighted signal s0 and bvec and gradients. eig can be {l1, l2, l3}, {{l1, l2, l3}, {e1, e2, e3}}, {{l1, l2, l3}, "Random"}, {{l1, l2, l3}, "RandomZ"} or {{l1, l2, l3}, "OrtRandom"}. Uses Tensor internally.
