Benchmarking R-GMA and Hello World Globus

R-GMA testing is now complete and I have moved on to Globus.

I have written and completed the tests for R-GMA and have been slogging away at doing the same for Globus. There are many pages of notes documenting this process on the Wiki. I found a bug in R-GMA which after talking with the developers we agreed to hack around (it added around 2 seconds to each query which is a lot when you are measuring 10s of milliseconds). I have found that every example for Globus code stems from the StickyNote tutorial they released with GT4. It has taken more than a week for me to understand enough to be able to do what I need for the tests and we have had to make some compromises in order to get past problems which I could not overcome. I have learnt a lot about how Globus works and how the high level terms everyone uses when describing the Globus Toolkit actually map onto the implementation.
