Under each class I listed all the APIMethod/APIFunctions and all the

What makes it frustrating is that it is tedious to keep up this sort of a

At the bottom of this page:

you can see a model that cr5 generated automatically from the code.

I can't remember offhand what he used to generate it -- pretty sure it
was something
he wrote himself -- but I think if we are going to put any real effort
into this, we should
be using his tool... at least for what amounts to the data entry part.
Moving around
the nodes so that everything looks nice... that can be done afterwards.

One thing is for sure, though, is that no one should burn any cycles on an
actual model until we put out the 2.7 release... or at least the rc1 thereof.

Chris? What do you say.
