Detailed Description

A user has to execute the algortihm suggested by the SchedulingDecision, or the library will not work. The user can determine the algorithm to excute by calling getNameofChoosenAlgorithm(). The user can then measure the execution time of the algorithm by using an AlgorithmMeasurement object.
