/**
 * Top-level interface for plugins. Plugins discoverable at runtime must
 * implement this interface and be annotated with @{@link Plugin}.
 * <p>
 * There are several different kinds of plugins:
 * </p>
 * <ul>
 * <li>{@link RunnablePlugin} - plugins that are executable as modules.</li>
 * <li>{@link ImageJPlugin} - executable plugins that perform a discrete
 * operation, accessible via the ImageJ menus.</li>
 * <li>{@link Tool} - plugins that map user input (e.g., keyboard and mouse
 * actions) to behavior. They are usually rendered as icons in the ImageJ
 * toolbar.</li>
 * <li>{@link Display} - plugins that visualize objects, often used to display
 * module outputs.</li>
 * <li>{@link PreprocessorPlugin} - plugins that perform pre-processing on
 * modules. A {@link PreprocessorPlugin} is a discoverable
 * {@link ModulePreprocessor}.</li>
 * <li>{@link PostprocessorPlugin} - plugins that perform post-processing on
 * modules. A {@link PostprocessorPlugin} is a discoverable
 * {@link ModulePostprocessor}.</li>
 * </ul>
 * <p>
 * What all plugins have in common is that they are declared using an annotation
 * (@{@link Plugin}), and discovered if present on the classpath at runtime.
 * </p>
