text: Title: Add examples for how to use consumer methods in documentation
  Body: Suggested by @Shanoir on Gitter:
  
  > One thing that I can suggest though: Overall the documentation of uplink is very nice. it clearly lays out how the API classes can be set up, and how to use the decorators. However, there is almost no examples available for the "use" of the methods. I think that across the board, providing these usage examples could really help newcomers get onboarded on the library :)
