        /*** This module is used by LODTree to simplify leaves of a tree. It contains functions that generate simplified
        versions of 3D objects made out of quads (represented as pairs of texture-mapped triangles). Given a 3D object, this
        module computes a sequence of geometric transformations that reduce the object’s geometric detail while preserving
        its appearance.\n\n

        For each simplification step, the module returns a simplification sequence containing the leaf collapsed, the two 
        leaves being removed, and the resulting leaf for that contraction.\n\n

        
Inputs:\n
        - A pointer to the Geometry::Mesh object containing the tree to be simplified.
        .

Outputs:\n
        -# The simplified mesh, contained in a Geometry::Mesh object.
        -# Simplification sequence, represented by a Geometry::TreeSimplificationSequence object.
