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.  
I hate to bring this to the party so late :/ Nowadays new client classes aren't written, there is one client that rules them all (lib/cb/client.rb). To use this client, you feed it request objects that define things about the API being hit (example: https://github.com/cbdr/ruby-cb-api/blob/master/lib/cb/requests/application_external/submit_application.rb).

So, the question is: do we take the time now to convert this to that way now, or since this way works, we let it into trunk, and then go back later to update this flow to the current way? My primary inclination is to say we should change it to the request + client way now, but I realize that this back and forth in PR mode creates a good deal of churn and frustration. That being said, changing it later will be a pain in the ass since this will be consumed in the front-ends as it is now, and those points of consumption will require updating too. Anyone have any thoughts on this?
