SDK

### Update 1
* Adds Federal SDK in ```lib```
* Configures ```lib``` directory in ```config/application.rb```
* Adds ```config/secrets.yml``` for SDK API keys. 

### Update 2
* Adds basic wiring for the SDK
* New Company model reflecting the API columns

I'm having a lot of trouble configuring this but I'm still optimistic. 
It's definitely getting and returning data, but not correctly parsing the thread. 
If anyone wants to pull this down and give it a spin, feel free. I'm still really optimistic. 
I am debugging this by running code in the working sample and then copying it in to the app. 
I've been successful in getting data back in rails console, so I *should* be able to do it in browser. 

Team @mbacksmeier @priyamathew I will email out the secrets.yml file for your local installs <del>tonight</del> soon.
(You can register your own API keys and drop them in a secrets yml too if you want asap access--should work right out of the box. :smile: )
