adding texture to each sub object

[farshizzo]

When applying a texture to an object, you can optionally specify the name of the sub-node you want it to be applied to. If your model contains a sub-node named palace then you can apply a texture to it using the following sample code:

# Apply texture to first unit
model.texture(tex1,node='palace')

# Apply texture to second unit
model.texture(tex2,node='palace',unit=1)
