officegen-dbb/test/test-xlsx.js

Modification of Ziv Barber's officegen, to provide a reasonable way to have line breaks in table cells.

//======================================================================================================================
// TEST SUITE FOR OFFICEGEN
// This generates small individual files that test specific aspects of the API
// and compares them to reference files.
//
// The comparison is based on string comparisons of specified XML subdocuments.
// Comparing PPTX files for exact-bytewise equality fails because the doc properties include the creation date.
// This method tests a defined set of XML subdocuments for string equality.
