ULFM Repository Change

To better accommodate management of the ULFM repository, the URL has changed. It can now be found at:

https://bitbucket.org/icldistcomp/ulfm/

All of your previous SSH keys will continue to work. All you need to do is change your .hg/hgrc file to point to the new repository.

New Usage Guide

To clarify the difference between installation/setup and usage, the old Usage Guide has been moved to ULFM Setup and a new Usage Guide has been put in place to provide instruction and examples for using ULFM constructs in MPI code. For now, this example section provides the code outlined in the ULFM specification, but this will eventually be amended to include more complete and unique examples. You can find the both of these pages in the menu bar, under User Level Failure Mitigation.
