Comments

OtherMaterial is now ExternalMaterial and is a utility using a structure similar to OtherMaterial

ExternalAid was removed from Statement to clean up and distinguish that object. Multiple ExternalAids can be used in an instrument design via ProcessStep.

And then later...tried to introduce another object variously referred to as ExternalAid or OtherMaterial to refer to external stimulus materials used in data capture instruments (e.g. images, URNs, other stimulus material). But OtherMaterial already exists as an object in Simple Codebook. Where should OtherMaterial live? Can it live in two models at once?
