Removed/commented out/tagged some unused local variables.

Added a JUnit test for the new Trie that fails at present since the Trie is
case-insensitive.  Running JUnit tests is not something our build system
knows about at present, but Eclipse 2.0 makes it very easy.

Fixed a few compiler errors due to imports I'd forgotten.
