Lei Le, Martha White

* Updates to previous version include a small modification to Proposition 2, to only use normed regularizers, and a modification to the main theorem (previously Theorem 13) to focus on the overcomplete, full rank setting and to better characterize non-differentiable induced regularizers. The theory has been significantly modified since version 1
