Read and write single file dicom volumes

Two functions that allow to read/write 3-D volume data from/to the DICOM format.

Two functions that allow to read/write 3-D volume data from/to the DICOM format. The volumes are stored/read to/from a zip-file that contains DICOM slices. This format is very useful as many DICOM tools allow the import of sliced DICOM volumes. However, often this involves lots of files. Thus, the slices are automatically zipped up in order to retrieve a single file that can be easily handled.
