Addition of profile, fill in and wavefront properties in sloan ordering.

[KC1706]

As i was inspecting the codebase i found an implementation of sloan oredering which has description of ordering the adjacency to reduce bandwidth, profile ,wavefront ,fill in properties which are particulary useful for sparse matrix computations and finite element analysis, but only bandwidth property is calculated but there is no implementation of profile,wavefront and fill in properties which are also useful for storage optimisations. Right? Sloan ordering aims to minimize all these properties, but they're not perfectly correlated. A low bandwidth doesn't guarantee low fill-in. Therefore calculations for all these properties should be implemented. right? I am open to discuss on this topic
