Detailed Description
JointActionObservationHistoryTree is derived from TreeNode, and similar to ObservationHistoryTree:
JointActionObservationHistoryTree is a class that represents a wrapper for the JointActionObservationHistory class. An JointActionObservationHistoryTree actually represents a node in the tree of observation histories. But each node also specifies a (sub-)tree so there is no actual difference between a tree and a node. This implementation assumes that ActionObservationHistories are always contained in exactly 1 JointActionObservationHistoryTree: i.e., deleting an object of JointActionObservationHistoryTree will free the memory of the node and the subtree represented by it as well as the memory of all the contained ActionObservationHistories.
A difference with ObservationHistoryTree is that here a successor is specified by 2 indices. One option would be to combine these into a joint index, but this would add calculation every time we're traversing the tree. Instead this class defines 2 types of nodes: ones that specify the action successor (A_SUC) and ones that specify the observation successor (O_SUC). Only the A_SUC nodes contain actual ActionObservationHistories, O_SUC nodes are 'intermediate nodes' and no operations should be performed on them.
