RMC .NET library

The purpose of this code is primarily for signing transactions, and while the code can do a bit more than what is shown here, at this stage, it may change without warning.

Transaction signing

Signing is done with either ecdsa/rfc6979 or ed25519. See ripple-keypairs for how to generate a seed/secret, encoded in base58.
