/**
 * An object that provides reporting options.
 * <p>
 * Tasks that produce reports as part of their execution expose configuration options of those reports via these methods.
 * The {@code Reporting} interface is parameterized, where the parameter denotes the specific type of reporting container
 * that is exposed. The specific type of the reporting container denotes the different types of reports available.
 * <p>
 * For example, given a task such as:
 * </p>
 * <pre>
 * class MyTask implements Reporting&lt;MyReportContainer&gt; {
 *     // implementation
 * }
 *
 * interface MyReportContainer extends ReportContainer&lt;Report&gt; {
 *     Report getHtml();
 *     Report getCsv();
 * }
 * </pre>
 * <p>
 * The reporting aspects of such a task can be configured as such:
 * </p>
 * <pre>
 * task my(type: MyTask) {
 *     reports {
 *         html.enabled = true
 *         csv.enabled = false
 *     }
 * }
 * </pre>
 * <p>
 * See the documentation for the specific {@code ReportContainer} type for the task for information on report types and options.
 * </p>
 *
 * @param <T> The base type of the report container
