[x3d-public] minecraft to X3dom

[tom sparks]

I have been developing a toolchain that can convert a minecraft 
schematic[1] file to X3D

tools:
* blockmodel[2]
* aopt
missing a lightmap generator[3]

example https://tomasparks.github.io/temp/minecraft2x3d/test_x3d.html

bugs:
camera not set (click: Show everything)
texture seams
missing transparency
missing sky

[3] looking at using blender, but I have not found a automated way of 
doing lightmapping :(
