Closes#15
For better logging I'm going to inject the rocksdb info_logger into the C++ Wrapper classes
=> The classes on the options object have a member to a DB specific logger
=> This c++ classes can only belong to a SINGLE db
=> For simplicity make this requirement also for the options object itself
