var valueForPoints = nameMapper.valFor( 'Points' )

'week' : 'chapter',
'course' : 'course',

});

var valueForExam = nameMapper.valFor( 'exam' )
console.log( 'valueForExam :',valueForExam );
// valueForExam : discussion

var valueForPdf = nameMapper.valFor( 'pdf' )
console.log( 'valueForPdf :',valueForPdf );
// valueForPdf : downloadable

try
{
var values = nameMapper.keyFor( 'downloadable' )
}
catch( err )
{
console.log( 'Unknown value downloadable, because this value has duplicates' )
