Download parallel JAR file with all dependencies

This module provides a very basic support for the parallel computing of tasks (Engine class) and entries of a matrix (MatrixEngine). This is basically just a wrapper around the java standard functionality for parallel computing (mainly the Standard Thread Pool and the Future interface). Additional functionality is provided by the ProgressReporter interface, which can be used as a hook to provide information on the current state of the parallel computing task to other modules or the user.
