+ * Title:        EdgeCloudSim - Custom VM Cpu Utilization Model
+ * 
+ * Description: 
+ * CpuUtilizationModel_Custom implements UtilizationModel and used for
+ * VM CPU utilization model. In CloudSim, the CPU utilization of the VM
+ * is a simple counter. We provide more realistic utilization model
+ * which decide CPU utilization of each application by using the
+ * values defined in the applications.xml file. For those who wants to
+ * add another VM Cpu Utilization Model to EdgeCloudSim should provide
+ * another concreate instance of UtilizationModel via ScenarioFactory
+ *
