This class satisfies the @link DeXSSChangeListener interface and offers
a command-line utility for applying DeXSS to files. It reports a possible
failure for any files that don't change.
TODO: Do a better job of testing or expected removal and non-removal
of XSS code.
This command-line test program processes the specified files or literals, and for each one
prints to System.out the following:
the file name (if any)
Any change messages from DeXSSChangeListener
Serialized XML result
A summary indicating whether the input changed or not (based on whether there were any XSSChangeListener messages)
TODO: A better test and regression harness.
