BehaviorChain is a class which chains together multiple behavior.  BehaviorChain is in itself a
behavior, and behaves and can be used accordingly.  BehaviorChain also supports recursive hooks to
be set on its constituent behaviors.  ChainedBehaviors should be specified in <Args> as follows:

<ChainedBehaviors>
    <Id>behavior1Id</Id>
    <Id>behavior2Id</Id>
</ChainedBehaviors>

Behaviors may also be appended programmatically via the appendBehavior method.

Recursive hooks should be specified with Python dict syntax as follows:

<RecursiveHooks>{'behavior1Id':'hookid'}</RecursiveHooks>

Behavior Chain manages all recurrences that its constituents propogate.  At this point, it does not
support recurrences in its hooks.
