The Stream Filter archetecture is finished, it's actually much cooler than I
had anticipated, and much cleaner. I'll have to add some documentation to it, because it's not really obvious how any of it fits together from the outset, although I have to say that the bzip2 test program is the easiest general bzip2 compression program I've ever made...it just goes :) Decompression in Bu::BZip2 isn't finished yet, but that's ok, it's coming soon.

11 * Data filter base class. Each data filter should contain a read and write
12 * section. Effectively, the write applies the filter, the read un-applies
13 * the filter, if possible. For example, BZip2 is a filter that compresses
14 * on write and decompresses on read. All bi-directional filters should
15 * follow: x == read( write( x ) ) (byte-for-byte comparison)
16 *
17 * Also, all returned buffers should be owned by the filter, and deleted
18 * when the filter is deleted. This means that the output of a read or
19 * write operation must be used before the next call to read or write or the
20 * data will be destroyed. Also, the internal buffer may be changed or
21 * recreated between calls, so always get a new pointer from a call to
22 * read or write.
23 *
24 * The close function can also return data, so make sure to check for it,
25 * many filters such as compression filters will buffer data until they have
26 * enough to create a compression block, in these cases the leftover data
27 * will be returned by close.
