One thing I forgot to mention in my email about sparse matrices earlier is support for band diagonal and block band diagonal matrices. They occur often enough in problems, but also can arise in the construction of preconditioners. In those cases we should think about supporting
1. Constructor to build band diagonal matrices from a set of vectors.
2. Constructor to extract a set of bands from a given sparse matrix.
3. Band diagonal solvers.
