support for using pandoc with citeproc; documentation

 The pandoc-citeproc library exports functions for using the citeproc
 system with pandoc. It relies on citeproc-hs, a library for rendering
 bibliographic reference citations into a variety of styles using a
 macro language called Citation Style Language (CSL). More details on
 CSL can be found here: http://citationstyles.org/ .
 .
 This package provides the documentation for a library for the Haskell
 programming language.
 See http://www.haskell.org/ for more information on Haskell.
