 * A Module is an encapsulated piece of functionality with inputs and outputs.
 * 
 * There are several types of modules, including plugins (see
 * {@link PluginModule}) and scripts (see {@link ScriptModule}),
 * as well as {@link Workflow}s, which are directed acyclic graphs
 * consisting of modules whose inputs and outputs are connected.
 *
 * The Module interface represents a specific instance of a module,
 * while the corresponding {@link ModuleInfo} represents metadata
 * about that module, particularly its input and output names and types.
