Database.create() should throw DatabaseException
Run the following code twice, and the second iteration will throw
CodernityDB.index.IndexException('Already exists') from
db = Database('/foo/bar') db.create()
If it is an error to
create a database which already exists, then perhaps there should be some exception thrown which is more appropriate than
IndexException. Also, http://labs.codernity.com/codernitydb/api.html#database should indicate that
create() throws an exception.
