renamed example api files, added google api example

Hi Hugh,

I've added the google api calls and refactored the names of the example api classes.  It seems that the only methods that are actually being wrapped by hystrix are method3 and method4.  I don't think any of the google api methods are wrapped.  Do you get those results as well?

I have some thoughts about next steps, but I want to be sure that the google api stuff is actually being wrapped in a hystrix command before I try to move forward...

Let me know if you'd like changes to this pull request.

Thanks!  Rebecca
