Delete range

The code does not delete the column family, but rather all entries within the range.

Suggested change

	* Removes all entries from the RocksDB database by delete the column family
	* Removes all entries in a RocksDB database column family using an uncapped range.

or something like that. GitHub won't let me fix the next line, so it will need to be manually removed.
