/**
 * Annotation that marks a method to be called when a plugin is loaded.
 * 
 * Intended for use by plugin developers to mark a method of an
 * extension implementation to be called during plugin load time.
 * 
 * The semantics of the method marked with this annotation is as follows.
 * 
 *     There should atmost one method in the implementation that should have this annotation.
 *     The method should be public, non-static.
 *     The method should take only one parameter- {@link com.thoughtworks.go.plugin.api.info.PluginContext}. Return values will be ignored.
 *     This annotation will not be inherited along with the method.
 *
