PR - Include Source generation script/Change domain

[Arvinds-ds]

1. Include observations.r and observation.tests.rgeneration scripts inobservations/src`
2. Change domain for data files and rst files to a new URL
3. .gitignore included csv file and it ignored the datasets.csv file which was required for generation

Is this PR ready to review? Looks like it still stores all the rst files.

My bad. Forgot to remove the doc folder. Pls see latest commit

Looks great! One comment: Travis seems to take >30 minutes and is timing out, whereas in #20 it only took 12 minutes. In principle, the only change is the download server. Is this slowdown really because of the download?

[Arvinds-ds]

I noticed that. I think because Travis and Github are well integrated, it is fast. The flip side is that I was testing it locally when I was @ Columbia and it took < 200 secs and all tests passed. I am ssuming Travis has some restrictions on downloading data from external servers.

Also I notice randon connection errors in the travis build log for e.g. affairs.py where as on my local machine it works..

Also, when I reran the tests again locally, it passed

[dustinvtran]

Got it. This sounds like a pervasive issue which is relevant to this PR but is more about #23 and how to handle Travis downloading many data sets. I propose merging the PR as is and leaving that issue open. Thoughts?

[Arvinds-ds]

Agree. For review purposes, Would request you to clone the repo and run tests locally and verify. It works at my end, but need you to validate it..

[dustinvtran]

Done!
