Algo_hash_full::Algo_hash_full	(	int	bsize,
		SnapshotVector	DATA,
		const string	OS_DATA_NAME,
		int	MAXNUMSTONES = `50`
	)

Basic notes:

For searches, data is used. It maps hashCodes to positions in the file os_data. At the specified position of the file, all game ids etc. where a position with this hashCode occurs are listed.

During processing, a multimap data_p is used which maps hashCodes to single hits. This data is written to os_data (together with the data previously available, if any) in get_data.
