DokkaMultiModuleFileLayout

Will point to a subfolder inside the output directory of the parent. The subfolder will follow the structure of the gradle project structure e.g. :parentProject:firstAncestor:secondAncestor will be be resolved to {parent output directory}/firstAncestor/secondAncestor

Will link to the original AbstractDokkaTask.outputDirectory. This requires no copying of the output files.
