[Bf-python] Getting armature hierarchy

[Tron Thomas]

I've been keeping up to date with the Python API changes that have been 
taking place in Blender.  And it looks like most of the stuff needed to 
exported skeletal animation is available.  A while back I posted about 
the need to get the hierarchical relation of all the bones in the armature.

It seemed that this would be accomplished by calling the getChildren 
method on a bone and that method would return only the immediate 
children of the bone.  Another method named getAllChildren was supposed 
to provide all bones depended from the specified bone.  So far it looks 
like getChildren is still returning all descendants, and the purposed 
getAllChildren method doesn't exist in the API's.

I'm wondering if this got over looked in all the development that has 
been happening and what is going to happen.
