[structure] Rename *ing packages
The packages that have "ing" suffix in their names (like logging, searching and so on) should be renamed, because they're not satisfying out project structure requirements (I think, searching is a process not and entity). Their names are too long, exhaustive and do not look similar with other package names.
The top-level package called "logging" should be renamed into "util". As for "searching", you may name it shorter (like "search") or delete it, because it is not quite clear why there is a "searching" package inside "efsm.extractor.conflict".
