USL-class

This class encapsulates the Universal Scalability Law. Use the function
<code><a rd-options="" href="/link/usl?package=usl&version=1.8.0" data-mini-rdoc="usl::usl">usl</a></code> to create new objects from this class.

The Universal Scalability Law is a model to predict hardware and
software scalability. It uses system capacity as a function of load to
forecast the scalability for the system.
