- Updated changelog to reflect changes from 2.0 to 2.1

- Updated readme and description of the examples

This document describes modifications in the CloudSim classes from CloudSim 1.0 beta to CloudSim 2.0
-----------------------------------------
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.

......@@ -52,11 +52,12 @@ Here is the description of what each example does:
CloudSimExample1.java : shows how to create a datacenter with one host and run one cloudlet on it.
CloudSimExample2.java : shows how to create a datacenter with one host and run two cloudlets on it.
The cloudlets run in VMs with different priorities.
The cloudlets run in VMs with the same MIPS requirements. The cloudlets will take the same
time to complete the execution.
CloudSimExample3.java : shows how to create a datacenter with two hosts and run two cloudlets on it.
The cloudlets run in VMs with different priorities. However, since each VM
run exclusively in each host, less priority will not delay the cloudlet on it.
The cloudlets run in VMs with different MIPS requirements. The cloudlets will take different
time to complete the execution depending on the requested VM performance.
CloudSimExample4.java : shows how to create two datacenters with one host each and run two cloudlets on them.
