$type	database type:
	File - outputs database into a file
	MySQL - creates a SQL database
	BerkeleyDB - creates a BerkeleyDB database
$dbName	database name.

Note 1: If the database type is File, the command will save the data into a number of files, e.g. $dbName.id11 for all ID objects of size 11 that sendSelf() is invoked upon.

Note 2:The invocation of this command will add the additional commands save and restore to the OpenSees interpreter to allow users to save and restore model states.
