R1, is the nuclear norm the important regularization? #16

Finish filling in references and context about the norm simplification to enable the theoretical analysis.

Checked in L&S demixing [27] that there is no simplification from objective with two norms to objective with nuclear norm. There's only nuclear norm in the convex approximation to the NP-hard problem.

Continue checking the others.
