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.

@brief Implementation of a discrete wavelet transform (DWT)

The functions in DWT.C have for goal to realize forward and inverse discret wavelet
|

transform with filter 5-3 (reversible) and filter 9-7 (irreversible). The functions in
|

DWT.C are used by some function in TCD.C.
