Input text through Google Doc and display compiled Rmd

[lauracion]

Summary for one of the projects that came up while discussing #42

The objective is to write body text (as well as captions, etc.), in the google doc with very easy, flexible, and robust markup, and then import that information into a compiled document and mix it with code-generated outputs. rchie parses ArchieML for the purpose of pulling text written in Google Docs into R and uses it to build R markdown docs where the text came from Google Docs. The project consists on further advancing this - more details here.
