Updated Themes (markdown)
Update page to warn other people of outdated information as devs have made it clear they will not document https://github.com/hadley/ggplot2/issues/798
Link to gist rather than in line for easier updates and sourcing. I hope this is appropriate.
fix theme_minimal for use with version 0.9 (error was: "Error in convertUnit ... 'x' argument must be a unit object")
Warning message: New theme missing the following elements: legend.margin, legend.justification
Fixed formatting of some code blocks, marked code blocks with r so syntax highlighting works
set expand=c(0,0) to visualize more accurately the full spatial extent of the data
added Claudia's examples
improved example, fixed fullframe margins, made all themes functions
added theme comparison code+result
