Get resumes

This allows us to use the new Resume GET api that has been created via the Ruby-API-Gem.  This has 100% line coverage for all lines added.  
yah, that line is long and unwieldy.  that is what i had in the beginning but it is hard to understand everything that is going on in that line.  there is a gsub after pulling a url, pulling of things for the query string (which you kept as a sprout method), there is the api_client build (which is done via a sprout method already) and there is the cb_get call.

The line is too long.  then i set things like
```ruby
url = Cb.configuration.uri_resume_get.gsub(':resume_hash', args[:resume_hash])
response = api_client.cb_get(url, query: query)
Cb::Responses::Resumes::ResumeGet.new response
```

then i turn url into a sprout method to remove that line.
leaving me 

```ruby
response = api_client.cb_get(url, query: query)
Cb::Responses::Resumes::ResumeGet.new response
```

so i just changed response into a sprout method of its own.  This was a somewhat organic way of this splitting it self up.
