The javascript excel support files seem to have vanished:

The  js/infragistics.documents.core.js file does not exist, maybe the file is now js/modules/infragistics.documents.core_core.js ?

The js/infragistics.exel.js file does not exist, maybe the file is now js/modules/infragistics.exel_core.js?

Our Issue

When exporting using the above found js files, we are now getting errors when attempting to add a worksheet to the workbook:

var workbook = new $.ig.excel.Workbook($.ig.excel.WorkbookFormat.excel2007);
var sheet = workbook.worksheets().add('Sheet1');

I receive the error:  'Object doesn't support property or method 'worksheets'' when trying to add 'sheet1' to the workbook

This is the link to the example we originally used:
