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.
