Add copyright headers *before* package statement
Remove duplicate blank lines

Fix misplaced package statements

This change also removes invalid license blurbs from various files, and
cleans up a few other minor header-related issues.
Move license-maven-plugin config off the server

Previously, we stored the license configuration at:

    http://code.imagej.net/licenses

But it was a pain to keep that updated and in sync with the codebase
here. It makes more sense to use a local license resolver.

Thanks to Johannes Schindelin for the idea.
Add project.rootdir that always points to toplevel

This is a bit of a burden to maintain when projects are added or moved,
but makes it easier to point to files off the root path. Usually doing
so is a bad idea anyway, but in some cases it is nice to have access to
shared configuration, such as the files in the license folder.
Fix GPL copyright blurbs in broken projects
Allow condition's range to be configurable
Add adapter class to treat a PointSet as a RegionOfInterest

This class added for completeness. It can be eliminated if the

OPS: make PointSetRegionOfInterest::move() more functional
Provide setters/getters for some classes
