Detailed Description

JointPolicyPureVector represents a discrete pure joint policy.

Each of the individual policies is a PolicyPureVector - a deterministic mapping from observations to actions implemented by a tree. This class acts as a wrapper. It contains a vector with pointers to indiv. policies.

we delete the PolicyPureVectors pointed to: this means that we should not be able to add indiv. policies without copying them!!!
