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.
