Investigate the use of DRMAA to submit jobs to clusters.

Currently we have a Torque/PBS specific way of submitting jobs to clusters.

We could make it more portable by using DRMAA instead.

I tried using the Python DRMAA interface. It worked for simple cases, but seg-faulted for some more complex examples. It seemed that the author was looking for someone else to maintain it. I'm not sure that we should pursue this.
