"""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."""
