Initial commit of sample ReDBox alerts ingest file.
DCXMLmap.json modified to accept new <creator> tag with details as child
elements.  005_write_redbox.t now adds datasets to Fedora so that it can
test whether repository IDs are being passed through or not.
005_write_redbox.t now checks all of the meta-metadata values in the
<header> element of the XML doc.
The libraries had drifted away from the tests - brought the 003 tests back
into line.
Cleaning up more bugs - 004 and 005 tests now check for the composite
'name' field
Fixed CoataGlue::Datastream so that it's using {access} on the dataset
object rather than {publish}.  All tests now passing.
