/**
 * This is the base class for all plugins that load and possibly transform files when they are loaded.
 * Different from other plugins, these plugins trigger for each file that is loaded (if they {@link applies} to the file).
 * See the {@link FlowrAnalyzer.addFile} for more information on how files are loaded and managed.
 *
 * It is up to the construction to ensure that no two file plugins {@link applies} to the same file, otherwise, the loading order
 * of these plugins will determine which plugin gets to process the file.
 * On transforming a file, your plugin can indicate whether other plugins should still get to process the file,
 * by returning a tuple of `[transformedFile, <boolean>]` where a boolean `true` indicates that other plugins should still get to process the file.
 * One example of a plugin doing this is the {@link FlowrAnalyzerMetaVignetteFilesPlugin}.
 *
 * See {@link DefaultFlowrAnalyzerFilePlugin} for the no-op default implementation.
