Dear Julia,

Just getting to know tidytext, so not sure if this is a feature or a bug, but I noted that if one uses tidy on a tm corpus, it does take in the corpus-general metadata, but not the non-standard metadata that is provided by the user when they created the corpus (the so-called "indexed" metadata).

If one knows about it, it is not a big deal to add a line of code binding the metadata to the tidy object, but I think it may be useful to at least notify the user of the possibility.
