Refactoring lucis...

These days I've been spending a little time refactoring lucis. In these early stages of development, the public API is being continuosly changing, as I look for better ways to provide the intended service.

Through this process, I've faced what I think is one of the most difficult problems in computer science: naming things.

In this case, there are some classes that deserve names already used by Lucene (Query, Searcher, etc.), and many source files (from users of lucis) may reference both Lucene's and Lucis' classes. Even though this is not a problem, I don't like fully-qualified names, so I've had some thesaurus time :)
