DAX's back - Create DAX Measures in Excel 2013 without PowerPivot Add-in

I mentioned in my last post that it was possible to create DAX measures (and indeed Calculated Columns, KPIs etc.) without using the PowerPivot add-in but instead using AMO to do so. The facility has always existed in HAMMER but only as a hidden option that I often used to iterate quickly through a set of measure variations (or load standard sets) during model development; but I wasn't 100% convinced it was worth the effort to make it more production quality in order to add it to HAMMER's public interface. But, with the extraordinary removal of PowerPivot add-in as an option for all retail versions and all O365 SME versions of Office 2013, I decided to revisit the code and make it available as a new HAMMER command "PPMAKEMEASURES".
