[Bf-python] FaceNormals

[models at paposo.com]

I get some funny numbers with this script but I think it's got to do with
python's conversion of floating point numbers.

import Blender
cube = Blender.Object.Get("Cube")
mesh = cube.getData()
for x in range(6):
    print mesh.faces[x].normal

output:
[0.0,0.0,-1.0]
[0.0,0.0,1.0]
[1.0,-2.8312206268310547e-007,4.4703416079983072e-008]
[-2.8312206268310547e-007,-1.0,-1.0430819941120717e-007]
[-1.0,2.2351743211856956e-007,-1.3411043653377419e-007]
[2.384185791015625e-007,1.0,2.0861625671386719e-007]

which would otherwise be:
[0.0,    0.0,    -1.0]
[0.0,    0.0,    1.0]
[1.0,    0.0,    0.0]
[0.0,    -1.0,    0.0]
[-1.0,   0.0,    0.0]
[0.0,    1.0,    0.0]

I guess this could be detrimental if you need some accuracy.
