Oxygen framework for XSpec.
Reworked so can install without needing 'build' directory.  Added a template.
Treat attributes in the XSLT namespace (in expect) as for elements in the XSLT namespace: copy them to a namespace alias to not be interpreted in the compiled stylesheet.
Fixed bug with variables appearing before x:call in a scenario.
Removed oxygen PI for the schema.
Applied patch submitted for issue 28.
Generate a local variable instead of a global variable declaration.
added version attribute (issue 31)
Added use of 'xspec.properties' file for easier customising.  Added description.
Die if compilation fails (+ typos), see issue 34.
Commented out the uses of the command open, specific to Mac OS X.
Adapted the command open to use either open or see (open is specific to Mac OS X).  See issue 33.
The inline context node generated an error when used with a x:context/x:param.
Added comments and a new variable.
Use now the environment variables XSPEC_HOME, SAXON_HOME and/or SAXON_CP.
Added support for XQuery in the shell script.  See issue 29 and 33.
Do not check for xspec.bat anymore in the shell script, but for one of the stylesheet, which makes more sense (the batch can be legitimately removed on a Unix system).
New tests.
Handle several nodes properly in XQuery.
Added the  parameter to the x:output-scenario.
