Python script that reads 3d file and writes a javascript file

[Michael Lake]

Hi all

My modified version of David Molnar's and Wookies python script that turns the
3d into json is at: http://www.speleonics.com.au/mikes/software/3dtojson.py
This prints lablels fine but still has the E-W swapped. It might be a simple
matter of changing sign of some of the variables in that python script.
