/**
 * A task that has no result and may throw an exception.
 * Implementors define a single method with no arguments called {@code run}.
 * 

 * 
The {@code Task} interface is similar to {@link Runnable},
 * in that both are designed for classes whose instances are potentially
 * executed by another thread.
 * A {@code Runnable} however can not throw a checked exception.
 * 

 * 
The class is intended to be use with custom executor wrappers {@link Runner} and {@link MonitoringTaskSubmitter}.
 *
 * @see Runner
 * @see MonitoringTaskSubmitter
