A comprehensive review and improvement of the entire project documentation

The documentation was updated in subclasses that effectively had any difference from the inherited class/interface.
In these cases, the tag {@inheritDoc} was used to extend the documentation in the subclass and avoid documentation duplication.

This was the last package updated from the 12 CloudSim packages.

Removed '(non-Javadoc)' comments of methods. These comments were used in overloaded methods, but
in fact, they don’t help in anything. They weren’t in javadoc format and have no effect.
And after all, when there isn't a javadoc in an overloaded method, the javadoc of the method in the 
super class is shown.

Inserted links to papers cited in several classes.

Documentation of packages org.cloudbus.cloudsim.network and org.cloudbus.cloudsim.power.lists improved.

Included some @todo's suggesting the assessment of some methods used to find an object inside a List in order to reduce search time. One option is to change some List objects by a HashMap. Other details can be seen at the @todo's inside the source code.

It was made clear that the classes are generators of pseudo random numbers following a given distribution.
A link to the distribution's Wikipedia page was included for each class.

Added a @todo informing the existence of a native java.util.function.Predicate interface, suggesting the removal of the created abstract class and the use of existing interface.

Added @todo suggesting the use of HashSet instead of arrays to improve the time to match events.

Some things aren't completely clear, such as how the provisioners classes should be used.
For instance, it wasn't explicit just from a provisioner itself that each PM hast to use its own instance of the provisioners such as ram and bw provisioner, and that it physical PE has to have its own instance of a PE provisioner.
The documentation was improved to make clear these assumptions.

Some @todo were added in order to make some improvements in the code clarity further.
For instance, some attribute names are confusing, such as "ram". It is not clear if it represents the capacity, allocated ram or anything else. However, the documentation of the attributes was accordingly updated to avoid these confusions.

The documentation of classes, methods and attributes were improved to make them clearer.
Many times the documentation of attributes and parameters just repeated the name of the attribute itself.
Some methods didn't have a clear explanation of their goals or lacked some important details that were included.
Some ambiguous terms such as "machine", that can mean a "virtual" or a "physical machine", where accordingly changed by the specific term to avoid confusion.
Some methods also had ambiguous meanings. Methods such as getUtilization of the UtilizationModel class return the utilization percentage of some resource. Other methods such as getUtilizationOfRam on HostDynamicWorkload class returns the absolute value of a resource usage (not percentage), what is not accordingly described in the documentation. These inconsistencies were corrected in the documentation.

Updated readme.

Fixed test failures for LogTest class due to hardcoded decimal separator. 
Some test cases was not passing due to decimal separator was hardcoded as comma, 
instead of getting the default decimal separator configured on the system.

./finishGoogleCodeGitHubWikiMigration: Moved ProjectHome.md from wiki branch to README.md in master branch.

Probability distributions implemented in CloudSim replaced by similar functions from Apache math commons.

* Set the Java source version to 6 in the main pom.xml, for consistency

Performance improvement of the Logger. Ubiquitous string concatenation when the logger is off is now avoided.
