[ODE] Trimesh creation problems

[Sergey Beloshitsky]

I have looked at your code,   think problem is in your data,  look at 
example source code that work with TriMesh
also you may look at ode-doc at trimesh geom class, there is some 
example code. 

make sure that Lib3dsPoint is sequence of 3 floats/doubles(for Double),  
it may also contain data at the end
Lib3dsFace(object->Model->meshes->faces) must contain chunks of 3 
indexes to data in Lib3dsPoint
