Preliminary Wrapper script released

A first stab at a wrapper script (jsawrapdr) has been released to users in Hilo. It matches the interface specified by CADC.

What it does:

• retrieve data files from the supplied list
• convert them to NDF if required
• determines the correct ORAC-DR instrument name based on the data
• checks that PRODUCT information matches for all files
• determines whether to run ORAC-DR or PiCARD
• converts products back to FITS

What it doesn't do yet:

• Provenance is not quite correct. It is possible to refer to a parent that will not be archived.
• There is no standardised approach to logging Standard Output and Standard Error
• dpCapture does not automatically copy products to the CADC transfer directory.

It's enough to get us started.
