Octave-forge package "incomplete-factorization"

1. Approach "Interfacing ITSOL"

Currently I plan to do something like this and started to work on an cloned SVN repository from octave -forge:

2. Approach "Stand-alone implementations"

A few hours ago I got an offer by Yousef Saad and Ruipeng Li to obtain stand-alone implementations of several incomplete factorizations. https://mailman.cae.wisc.edu/pipermail/octave-maintainers/2013-May/033874.html

I would favor to refactor them to native Octave data types internally and make them directly available as *.oct files for usage. By interfacing the ITSOL library I think there will be a too big memory and time overhead due to data format conversion.
