function nwbExport(nwb, filenames)
    %NWBEXPORT Writes an NWB file.
    %  nwbRead(nwb,filename) Writes the nwb object to a file at filename.
    %
    %  Example:
    %    % Generate Matlab code for the NWB objects from the core schema.
    %    % This only needs to be done once.
    %    generateCore('schema\core\nwb.namespace.yaml');
    %    % Create some fake fata and write
    %    nwb = NwbFile;
    %    nwb.session_start_time = datetime('now');
    %    nwb.identifier = 'EMPTY';
    %    nwb.session_description = 'empty test file';
    %    nwbExport(nwb, 'empty.nwb');
