1. Purpose

Create initial for two puncture black holes using a single domain
spectral method. This method is described in Marcus Ansorg, Bernd
Brügmann, Wolfgang Tichy, "A single-domain spectral method for black
hole puncture data", PRD 70, 064011 (2004), arXiv:gr-qc/0404056.

This thorn was extended to include source terms to be able to handle
matter with the same restrictions as the BHs before plus zero
momentum/angular momentum (K_{ij} = 0).
