/**
 * Builds a table for printing simulation results from a list of Cloudlets.
 * It defines a set of default columns but new ones can be added
 * dynamically using the {@code addColumn()} methods.
 *
 * The basic usage of the class is by calling its constructor,
 * giving a list of Cloudlets to be printed, and then
 * calling the {@link #build()} method.
