Hi Brian,

It's a list of boolean (true/false) values, it needs to have one entry for each corner and value of true means that corner will be filleted and false means it won't be filleted.

The part that's a little tricky is making the list the right length so that it has one entry in it for each possible fillet location. I've put in a .numVertices property on the fillet factory for the next beta release to make it easier to know how many entries should be in that boolean list.
