* plugin/file: Rename do to walk, cleanup and document * This renames Do to Walk to be more inline with Go standards. Also make it return an error instead of a bool. Also give give walk access to rrs. Alternatively e.m could be exported, but just access the map of rrs should work as well. Another alternative would be adding a whole bunch of helper functions, but those need grab and return the data. Just having access to the rrs should be easiest for most Walks. * It adds Type and TypeForWildcard to show the different functions * *Removes* the identical RR check when inserting; this was only done for A, AAAA and MX and not finished; removed under the mantra garbage in garbage out. * Reuses Types to return all the types in an *tree.Elem Signed-off-by: Miek Gieben <miek@miek.nl> * better comments Signed-off-by: Miek Gieben <miek@miek.nl>
