Description
Partially re: #17 (comment), I'm currently coming across the problem of seeing all {to,from,as}_bytes functions documented with nothing more but stubs.
I do, for example, not know if the formatting of those bytes are specific to ed25519-dalek, if they're generic DER formats, or if it is any other kind of format, I do not know what I can feed it to give me a valid result, and figuring this out requires me to annotate my own code as to what the functions from this library are actually doing.
Also, the documentation here comes over as unnecessarily hostile to the user of this library;
Absolutely no validation is done on the key. If you give this function bytes which do not represent a valid point, or which do not represent corresponding parts of the key, then your Keypair will be broken and it will be your fault.
