New team for GPU core work

With V Vishal leaving (now known as Dr. Vishal), we’ve brought on new people to work on GPU core work.  In particular, we have two of our strongest programmers working in this area: Mark Friedrichs and Adam Beberg.  Mark is working on the Chemistry side of the code (making sure the science works) and Adam is working more on the infrastructure side (making sure all the GPU craziness works — GPU’s are not like CPU’s to code and involve a lot more complexity).  In particular, the recent PS3 upgrades (Generalized Born implicit solvent or "GB") will be ported over to the GPU core and we’ll soon be doing on the GPU’s what’s working so well on the PS3 (more on GB on the PS3 later).
