Rdmft - Including Preconditioning

Florian Buchholz requested to merge rdmft into develop

Description

We tested the application of the preconditioner for the cg routine of rdmft. In all examples it converges faster with all the standard preconditioners (filter, jacobi, poisson). Filter seems to be fastest and is the default now.

News snippet

The CG minimizer of RDMFT supports now preconditioning.
