Rewritten Myrddin Docs

[Ori Bernstein <ori@xxxxxxxxxxxxxx>]

...and updating the docs lead to fixing and updating a bunch of really dumb
APIs.

    http://eigenstate.org/myrddin/doc/

Feel free to give it a read, point out bad APIs, and point out the confusing
bits of the reference.

Let me know if there are places where more information or examples would help
make things clearer.
