JPEG2000 XML BOXES reader writer

This couple of functions manages XML boxes in a JPEG 2000 file.

readBox - reads a single XML box
readJP2Boxes - reads all XML boxes
writeJP2Box - writes a single XML box
compactJP2boxes - flushes all boxes in file and reinsert them as a single one. This function also uses an xslt file to do a smart merging between xml data: this is useful if xml boxes are coherent with each other, otherwise malformed xml could lead to errors.

· MATLAB Release: R14
