SRU::Response - A factory for creating SRU response objects

    my $request = SRU::Request->newFromURI( $uri );
    my $response = SRU::Response->newFromRequest( $request );

SRU::Response provides a mechanism for creating the appropriate response object based on a request that is passed in. For example, if you pass in a SRU::Request::Scan object you'll get back a SRU::Response::Scan object with some of the particulars filled in.

The factory method which you must pass in a valid request object: SRU::Request::Explain, SRU::Request::Scan or SRU::Request::SearchRetrieve. If you fail to pass in the correct object you will be returned undef, with an appropriate error stored in $SRU::Error.

SRU::Resonse also serves as the base class for the three response types, and thus provides some general functionality to the child classes.

Returns 'searchRetrieve', 'scan' or 'explain' depending on what type of object it is.
