Ganga Quickstart Guide Complete

I have finished the last few sections of the Glasgow Ganga Quickstart Guide.

In particular I have covered bulk job submission using ganga.

Swetha and I used the methods described here to submit a batch of 12 of her jobs onto the cluster this afternoon. She's very pleased to have a scalable method to submit large numbers of jobs onto the cluster - previously she was limited to ~5 jobs on the computing service cluster, which she also had to run interactively. This is much better.
