Convenience starter of Exec
in the unnamed package.
This class / application exists in spite of the (good) rule that no
self respecting class shall dwell in the unnamed package. The only
purpose of life is the snugness to type java Exec ComplDemo
instead of java de.frame4j.Exec ComplDemo
As might be inferred this class' main() just
delegates to main of the
"real" Frame4J tool in its right package. That's all.
