Keygen example not functional.

[sneurlax]

The keygen example makes calls to various inexistent functions, including sign_key_userid. I've also tried traversing the source code back to keygen.php's inception (Jul 25 2011, I think,) and I can't get it functioning even then.

Is keypair generation a feature that is currently implemented? If so, where and how?

This example is functional in my fork https://github.com/singpolyma/openpgp-php
