Request MetaData

[josephlei]

Hi Ivan,

Thank you for building this application, it is immensely useful. I was just wondering if you would be open to publishing the meta data regarding the tags that can be used to define the downloaded files such as #{section} - #{lecture} so we can customize it further.

I can guess a couple, and have done so successfully.. it would be awesome if you could .md a list of all avail. options. Thanks again for the amazing work!
