Update QuickReference

[gecampbell]

The QuickReference should be a small, very simple reference to all API functions and their arguments. Right now, it has way too much descriptive verbiage that doesn't add much. Verbiage and examples should be moved to the User Guide.

I'm going to work on this for next release. I don't even know if we really need a quick reference because we have the Getting Started guide, an introductory Readme AND detailed API documentation for every service (with code samples).
