AtSigningAlgorithm class abstract

Interface for data signing. Data is signed using private key from a key pair. Signed data signature is verified with public key of the key pair.

Do not implement for new code. Implement AtSignatureAlgorithm instead — it is stateless (key material passed per call) and safe to share as a singleton.

Removed in v4. Will become sealed once all implementers move into this library, closing the hierarchy in favor of AtSignatureAlgorithm.
