Reads metadata files from Synapse (rather than user uploading) -- in #5 I will update the app so that it uses the user's login and permissions. Right now this just calls synLogin() (for ease of testing locally; this isn't deployed anywhere)
Checks individual IDs, specimen IDs, annotation keys and values in the manifest
Allows bookmarking of results (only for metadata files, not uploaded manifest)
