Description

New notions to be introduced:

  1. MmuAbstraction<T>: maps an MmuTransition to a T object or null.
    1. MmuAbstraction<T>: allows mapping MemoryAccessPath into List<T>.
      1. List<T>: represents abstract paths.
    2. BufferEventAbstraction: maps MmuTransition to a BufferEvent or null.
  2. AbstractPathExtractor<T>: given an AbstractionFunction and MemoryAccessType returns Map<List<T>, Chooser<MemoryAccessPath>> (where Chooser<T> is an interface with a single method T choose()).
    1. MemoryAccessPathChooser: implements a random-order-traverser-based chooser (collection of the extracted paths is supplemented on every choice).
