Strategies for indexing metadata in files

[awead]

ActiveFedora::File objects can contain metadata, but it is not indexed in Solr. There needs to be documentation about how to do that. The current strategy is to index the metadata in the ActiveFedora::Base object that contains the file, but this must be done via a custom indexer.

See #1098

If you want to retain indexing, why not use the datastream gem? https://github.com/projecthydra-labs/active_fedora-datastreams

@jcoyne I was referring more to binary files that have description attached to them, i.e. /fcr:metadata, but yeah, if you want an AF::File that is purely just description, the datastream gem would be the way to go.
