i haven't seen how Thomas uses the word, but btw, one instantiates a 
class, by creating an object. The object is "templated" according to the 
class. The behaviour is defined by a class. Even if internally all 
abstractions work from the same basic behaviour in pd, the fact that we 
call patching a kind of programming validates the idea that each 
abstraction file is a class.

An interface (aka protocol) is the set of what objects of a certain class 
can accept as arguments and messages (or signals), together with the set 
of what messages (or signals or I/O) the user can expect, and when. The 
more it works like other object classes, the less you may need to document 
it (depending on how the documentation is structured). A help file 
documents the interface of a class and not the class itself.
