ENG-355 File Sharing

Tomb needs to produce a data structure that includes all the information required to access a single file in a read-only way. This should include the reference to any specific entry point needed to find the required blocks to access the file as well as the encryption details to access that specific version of the file, I believe this is called the snapshot key in WNFS? The struct should be serializable and should try and keep it small.
