renamed and reorganized "jp3d" directory to "openjpeg3d". Is now a standalone directory, with independent cmake files. Done as it uses its own version of the openjpeg library and does not depend on the one currently developped. Will be removed from the trunk and stored in a branch.openjpeg3d@749

+@brief Implementation of a packet iterator (PI)

+

+The functions in PI.C have for goal to realize a packet iterator that permits to get the next

+packet following the progression order and change of it. The functions in PI.C are used

+by some function in T2.C.
