        /// Construction module for general multiresolution models.
        /** This module stores general mesh multiresolution
         *      representations using our own specific file format.
         It takes as inputs the strips provided by the
         stripification module and the edge collapse
         sequence computed by the simplification module.
         It builds a multiresolution representation and generates
         a LODStrips file.\n

         The LodStrips file begins with a line stating the name
         of the mesh file it refers to.
         This filetype has three different kinds of records
         storing the information required for the multiresolution
         model. All the records of the same kind are output following
         the right order.

         Those lines starting with a 'd' include:\n

         -# Strip to modify.\n
         -# Number of collapses.\n
         -# Number of vertex repetitions.\n
         -# Number of edge repetitions.\n
         .
         \n
         Those beginning with a 'p' include the number of 
         strips affected by a LOD change.\n\n

         And finally, the ones starting with a 'b' include
         all the information needed for collapses and repetitions.
         \n\n

Inputs:\n
- A strip set provided by the stripification module
(Geometry::Mesh class).\n
- An edge collapse sequence computed by 
the simplification module
(Geometry::MeshSimplificationSequence class).

Outputs:\n
- The module writes a file with the LODStrips information.
- It also writes the LODStrips mesh into a file.
