[ESS] Integration of pandoc using polymode+knitr

[Ahmadou Dicko]

Using the rmarkdown package, you can use ess-swv-run-in-R elisp function to
create ess-swv-pandoc (ess-swv-pandoc.el) and modify the R function
.ess_weaver to add rmarkdown::render option (ess_weave.R).
Make sure that that ess-swv-pandoc.el in your path and your R process use
the new .ess_weaver function.

Hope it helps
