/* Quick Copy or Drag & Drop BibTeX-style cite commands, such as "\cite{key}" from
 * This file is a wrapper around a modified version of the "BibTex" translator from Zotero 2.1.10, 
 * which uses available methods from that translator for extracting / generating a BibTeX-compatible cite key.
 * This Translator uses a greatly simplified doExport() function to output only "\cite{key}" on export.
 * By setting "Quick Copy" to use this translator (in Zotero 'Export' Preferences), you can 
 * Drag & Drop citations in the form of a Bibtex "\cite{key}" from Zotero.
 * There are a few variables near the top that allow simple control over the formatting of this exported content,
 * Such as which command to use (if any), and what to put between multiple items.
 *
 * Modified by:         Jonathan Whiteley (jaw)     jonathan [dot] whiteley [at] mail [dot] mcgill [dot] ca
 * Original tweaks by:  Andrew Leifer               leifer ( at ) fas ( dot ) harvard (dot) edu
 * Inspired by similar work by: Avram Lyon          ajlyon [at] gmail.com     
 */
/*TODO
 * There should be a more elegant solution, ideally by calling methods from the default '.bib' import translator,
 *   then picking up / overriding the export method to produce the desired output.

 * Multiple keys will be separated by `keySep`: default is a comma + space ", "
 * The cite key(s) will be wrapped in curly braces {}, with `citeCommand` appended to the front.
