Fixed Tests and Added Output as a parameter to _executeRequest
Updates to README.txt
added code from experiment with csw client
Added the first cut of a csw client instead of a url list. There is a test in place for the csw client. Fixed up other tests, they work and are a bit faster.
We'll see what this does... Merge branch 'csw_client_experiment' of https://github.com/dblodgett-usgs/pyGDP into csw_client_experiment
removing remnant of experimentation on this branch.
