extra newlines for working on xsl
in in inbook references now has uppercase I....
Initial thoughts on unit test framework for references
support for string-name, issue, etal
Second pass on unit testing references. Added code to support writing out of actual results and updating expected results with those files. Also no need to touch the source code if just adding test cases.
Tried to make it look like there is a test per file rather than all files being run by one test. Improved output.
ed used in in-book when only a single editor was listed.
support for collab elements that declare themselves the sort key for mixed-citations.

also, this is the first support for collab inside of journal articles, mixed with authors.
Updated expected files
Merge remote-tracking branch 'origin/xslPlay' into Exploration

Conflicts:
	base/src/main/resources/articleTransform-v1.xsl
Updated expected files to track changes for <et all>, <issue>, etc.

Also counting differences in the XML now to get an understanding of the magnitude of the change.
Added remaining articles for full regression test.

Format change to expected files based on Dave's changes to the XSL.
