// Original File:       ./cite/styles/cite_Vancouver.php
// Original Author(s):  Matthias Steffens <mailto:refbase@extracts.de>
// This Vancouver style was modeled after these resources:
// <http://www.library.uq.edu.au/training/citation/vancouv.pdf>
// <http://library.curtin.edu.au/research_and_information_skills/referencing/vancouver.pdf>
// <http://www.icmje.org/index.html> citing: <http://www.nlm.nih.gov/citingmedicine/>
// <http://www.nlm.nih.gov/bsd/uniform_requirements.html>
// <http://library.sun.ac.za//eng/help/infolit2002/bibvancouver.htm>
// based on 'cite_AMA.php'
// NOTES: - In the Vancouver style, the reference list is arranged numerically in the order in which references are cited in the text.
//          This isn't currently handled by this style
//        - For conference proceedings, you'll currently need to add the place & date of the conference in the proceedings title field
//          (e.g. "Proceedings of the 5th Germ Cell Tumour Conference; 2001 Sep 13-15; Leeds, UK").
// TODO: - abstracts, newspaper/magazine articles, patents & reports?
//       - arrange references numerically
//       - for newspaper articles, only the beginning page number of an article should be included (see: <http://www.ncbi.nlm.nih.gov/books/bv.fcgi?rid=citmed.section.41496#41607>)
//       - where to put (and how to format) editors of whole books that also have an author?
//       - see also inline comments labeled with TODO (and NOTE)
// Modified for use in biblio by Ron Jerome
