 * tar is a UNIX program for archiving.
 * Two types of operations are possible: concatenate / extract
 * Thus the name of 'gdcmtar' to concatenate a list of 2D slices into a multi frames
 * and the other way around: extract 2D slices from a multi frames image
 * It also support the fake multi frame image (CSA MOSAIC)
