adding requests, first pass

Signed-off-by: Daniel Halperin <dhalperi@cs.washington.edu>
.gitignore .coverage and .nodeids
add README.txt
improve setup.py following http://guide.python-distribute.org/creation.html
test_style: fix style

lol
connection.py: cleanup and fix json
connection.py: disable logging for now
connection.py: refactor when we add self._url_start to the path

Honestly, I find this rather awkward!
add connection test
test: mock out requests
refactor slightly, add another test
test query submission, validation, status, etc
cover only myria package -- following datalogcompiler
check util works
query: better testing of submit
test workers
test_query: simplify
