The AssocNetwork class keeps a network of AssocActions. Notice that it is derived from AssocAction, therefore it also behaves as an individual AssocAction. It means as a whole network can depend on other objects via its AssocDependencies or be owned by a higher-level AssocNetwork, allowing to create hierarchical associative structures. 

The AssocDependencies between AssocActions in the AssocNetwork define how the actions are tied together, how they depend on objects and on each other. For example, if one action modifies (writes) an object and another action uses (reads) the object, then the second action depends on the first one and the second action needs to be evaluated only after the first action has been evaluated.
