Refactored the LSM-indexes to use common abstract class. Added new ILSMComponent interface to represents the LSMComponents instead of passing Objects all around the place. Removed the component finalizers classes and cleaned the file manager API. Fixed couple of bugs. Cleaned the code and changed the names of many methods.
