This project contains vcd2svg, a program for generating schematic
illustrations of vertebral columns, visually similar to that of
Wedel (2009:supplementary figure 1):
	https://svpow.files.wordpress.com/2009/02/wedel-2009-supplementary-fig-1.jpg
It was first written to make Wedel and Taylor (2013a: figure 9):
	https://svpow.files.wordpress.com/2013/03/wedel-and-taylor-2013-bifurcation-figure-9-bifurcatogram.jpg
And then re-used to make Wedel and Taylor (2013b: figure 2):

Input is in the VCD (Vertebral Column Description) format, which is
defined for the first time in this project (but not yet documented).
Two such inputs (the ones we used for the 2013 papers) are
"bifurcation.vcd" and "pbj.vcd", and can be found in the "examples"
area.

These files are translated into SVG by the bin/vcd2svg script.
This is written in Perl, using the SVG library.
