automate running of qsubs with dependencies on SGE

[xguse]

as of now:

blacktie --prog all config.yaml --mode qsub_script

writes your individual qsub scripts but you have to submit them all by hand.

blacktie should be able to write a meta-qsub that will take care of submitting, monitoring successfull completion of dependent runs and progression to the next set of qsubs.
