added properties and classes for new CRAM log structures
copied tfjava files to tfmemory since more substantial changes are needed for proper reasoning about logged transforms
added lastAccessed field storing the time stamp when stored transform has been accessed the last time
simple garbage collector based on lastAccessed field instead of age w.r.t. current time
adapted tf memory to new garbage collection scheme -- reasoning over time works now also with multiple time slices after each other
removed duplicate class file
Made changes at the java side since  uima_uima_results table does not exist anymore.
