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');
