data: database storage

* replaced storage by a new version that utilizes sqlite for persistence. * added SqliteStorage to manage direct access to the database. * added testsuit for sqlite. * slimmed down the protected interface of the storage. * changed tests in StorageTestSuit to avoid using protected methods of the storage. * added functions to begin and commit a transaction to the storage. * removed GraphFilterTestSuite. * removed GraphFilterConductorTestSuite. * added Node and Edge constructor that takes id as parameter * added constructor for TokenComponentNameCached that accepts NameHierarchy as parameter * added TokenLocation constructor that takes locationId as parameter. * created respective construction functions in TokenLocatonLine, -File and -Collection. fortune cookie message = Recognition will come from unexpected sources.
