So Pose constraints are found (deep down) in the bPoseChannel struct of 
ob->pose instead of ob->constraints.  And only poses have IK or Action 
constaints.... from what I can see in the source.

I assume the constraints for Poses should be accessible as a bone 
attribute [sequence of constraints] as opposed to an object attribute?
