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

[Michael Lake]

Hi Olly and all

Okies I have fixed the python script that does the labels. That is now working
fine. Looks like my only error now is the js that swaps E-W. As you noticed Olly
it's correct in the 3d as ASCII and looking at the 3dtopos output. 

I think I'll have to wait for other who have lconv.py to check if they get E-W
reversed.
