class AAM[Exp, Abs, Addr, Time] extends EvalKontMachine[Exp, Abs, Addr, Time]
Implementation of a CESK machine following the AAM approach (Van Horn, David, and Matthew Might. "Abstracting abstract machines." ACM Sigplan Notices. Vol. 45. No. 9. ACM, 2010).
A difference with the paper is that we separate the continuation store (KontStore) from the value store (Store). That simplifies the implementation of both stores, and the only change it induces is that we are not able to support first-class continuation as easily (we don't support them at all, but they could be added).
Also, in the paper, a CESK state is made of 4 components: Control, Environment, Store, and Kontinuation. Here, we include the environment in the control component, and we distinguish "eval" states from "continuation" states. An eval state has an attached environment, as an expression needs to be evaluated within this environment, whereas a continuation state only contains the value reached.

KontAddr extends AnyRef
The store used for continuations is a KontStore (defined in Kontinuation.scala).
The store used for continuations is a KontStore (defined in Kontinuation.scala). It is parameterized by continuation addresses, that are element of the KontAddress typeclass.

State(control: AAM.Control, store: Store[Addr, Abs], kstore: KontStore[KontAddr], a: KontAddr, t: Time) extends Product with Serializable
A machine state is made of a control component, a value store, a continuation store, and an address representing where the current continuation lives.

Performs the evaluation of an expression @param exp (more generally, a program) under the given semantics @param sem. If @param graph is true, it will compute and generate the graph corresponding to the execution of the program (otherwise it will just visit every reachable state). A @param timeout can also be given.
