        For Any given resolution and object this module returns two thins: a set of triangle strips representing the trunk 
        and the branches at that resolution, and a triangle list representing the leaves at the same resolution. 
        \n\n

Inputs:\n
        - The module receives a file describing a multiresolution tree object.
        .

Outputs:\n
        - The module returns a strip set that represents the level of deatil demanded for the trunk and a triangle list 
        that representes the level of detail for leaves.
        .
