78*
79* Modified:  9-May-96 Paulo Nunes: Reformatted. New headers.
80*       14-May-96 Paulo Nunes: Changed TMNMVtabs according to VM2.1.
81*   04.11.96 Robert Danielsen: Added three new tables for coding
82*           of Intra luminance coefficients (VM 4.0)
83*      01.05.97 Luis Ducla-Soares: added VM7.0 Reversible VLC tables (RVLC).
84*      13.05.97 Minhua Zhou: added VlC tables for CBPYtab2 CBPYtab3,
85*   revised  CBPYtab
