Feature/issue94

• The API of Lapack_to_Tile/Tile_to_Lapack family function is modified to integrate the uplo parameter (This is done to enable the following points)
• A new option mtxfmt is introduced to change the allocation of the matrix.
  • 0: The matrices are allocated as a single big allocation
  • 1: The matrices are allocated tile by tile (Only with StarPU)
  • 2: The matrices are out-of-core (Only with StarPU)
• Fix issue #96 (closed) by adding an example at the end of the usage function
• Fix an issue with the descriptor copy functions that was using the incorrect get_blkldd/get_blkaddr functions.
