See #380 (comment).

Maybe we can add some API (to ObjectService? somewhere else?) to keep track of human-friendly types, such as:

String friendlyType = objectService.getHumanFriendlyName(Type type); // e.g. RandomAccessibleInterval => "an image"

(falling back to "an object"),
and then something like:

"This operation requires " + name + " of type " + type + "."

... to generate an error message such as:

This operation requires an image of type RandomAccessibleInterval.
