Documentation of package org.cloudbus.cloudsim.network.datacenter improved. 

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.

/** The safety parameter in percentage (at scale from 0 to 1).
* It is a tuning parameter used by the allocation policy to define
* when a host is overloaded. The overload detection is based
* on a dynamic defined host utilization threshold. This threshold
* is computed based on the host's usage history Median absolute deviation
* (MAD, that is similar to the Standard Deviation).
* This safety parameter is used to increase or decrease the MAD value
* when computing the utilization threshold.
* As the safety parameter increases, the threshold decreases,
* what may lead to less SLA violations. So, as higher is that parameter,
* safer the algorithm will be when defining a host as overloaded.
* For instance, considering a safety parameter of 1.5 (150%),
* a host's resource usage mean is 0.5 (50%)
* and a MAD of 0.2 (thus, the usage may vary from 0.3 to 0.7).
* To compute the usage threshold, the MAD is increased by 50%, being equals to 0.3.
* Finally, the threshold will be 1 - 0.3 = 0.7.
* Thus, only when the host utilization threshold exceeds 70%,
* the host is considered overloaded.
* Here, more safe or less safe doesn't means a more accurate or less accurate
* overload detection. Safer means the algorithm will use a lower host
* utilization threshold that may lead to lower SLA violations but higher
* resource wastage. Thus this parameter has to be tuned in order to
* trade-off between SLA violation and resource wastage.
