Bookfile: an immutable container file format

This crate is still under development.

Bookfile allows creating a file in Book format, by writing sequential chapters. A bookfile can be created in streaming mode, making it possible to create a Bookfile while writing it into a network socket or other streaming-only device. Any target supporting std::io::Write will work.

Each chapter contains a [u8] payload and is read independently.

The Book type represents a read-only Bookfile. Invividual chapters can be read using the std::io::Read interface. Seek and read_at are also provided, and work within the context of that chapter: the seek offset is the offset within the chapter, and a read at the end of the chapter will return EOF.

A chapter's offset, length, and id number are all kept in a Table of Contents stored at the end of the file. The TOC will be read when a Book is opened, but no chapters will be read until requested.
