Description

Given that #12 implements a distributed "static" SVD using [ScaLAPACK](http://www.netlib.org/scalapack/) and that [Elemental](https://github.com/elemental/Elemental) is deprecated, Elemental support should probably be removed. The [LLNL fork of Elemental](https://github.com/LLNL/Elemental) has stripped everything but support for BLAS Level 1 subroutines, so that fork won't serve our purposes.

The QRCP and QDEIM functionality also needs cleaning up.
