A few really minor changes.

Hi Stephen,

Long time no talk.  I finally got around to upgrading to your latest.  It's really nice man!  I like the new namespaces, etc.

These two changes seem like they'd be useful.  The first removes the assumption that the componentType is always an audio effect.  For example, in my project I add Apple's AUNewTimePitch unit to the graph.  It has a component type of kAudioUnitType_FormatConverter, which doesn't work without this change.

The second change is just to keep the externally packaged files from showing up in Git, which will be good from a contribution standpoint.

Thanks!
