pReplay

pReplay replays the dependency graph. It starts from the first activity which is loading the root html. Then according to the graph, it it encounters a network activity, it makes a request for the corresponding url, or if it encounters a computation activity, it waits for a specific amount of time (mentioned in the graph). Once a particular activity is finshed it checks whether it should trigger dependent activities based on whether all activities that a dependent activity depends on are finished. pReplay keeps walking through the dependency graph this way until all activities in the dependency graph have been visited.
