[Swift-devel] LQCD mapping

[Veronika V. Nefedova]

I'd like to mention that as a result of our 'play' last evening - we have a 
working LQCD workflow (chained genU execution) so the workflow could be 
given to Xian-He once the changes Ben has made to swift make it into trunk. 
My special thanks to Ben who came up with the mapper construction below 
that made the workflow work!
