* Various changes to the code to accommodate the use of `shiny::makeReactiveBinding`. The advantage is that the code generated for _Report > Rmd_ and _Report > R_ will no longer have to use a list (`r_data`) to store and access data. This means that code generated and used in the Radiant browser interface will be directly usable without the browser interface as well

# radiant.data 0.9.2.0
