cloudsim-2.1.1

---

Changes from CloudSim 2.0 to CloudSim 2.1

• The project has been migrated to using Apache Maven (http://maven.apache.org/). Maven simplifies
  java project management by providing various tools and plugins for project building, testing, and
  packaging, dependency management, etc.
• The directory structure has been changed to comply with the Maven specification
• The VmSchedulerTimeSharedWithPriority has been removed as well as the priority field from the
  Vm class. Users can have the same functionality by using the VmSchedulerTimeShared class and
  setting the MIPS requirements for VMs. See examples 2 and 3.
• Bug fixes, refactoring and removing obsolete code.
