		### sovrinDID.signMessage(message, signKey, verifyKey)
		Signs a message with the given signKey and verifyKey.

		* The message should be a string.
		* Both the signKey and verifyKey should be the signKey and verifyKey given from the `gen()` or `fromSeed(seed)` methods

		Returns a signed message as a Uint8Array (i.e. Buffer).

		Example:
		```js
		var sovrin = sovrinDID.gen();

		var signKey = sovrin.secret.signKey;
		var verifyKey = sovrin.verifyKey;
		var message = "Hello World!!";

		var signedMessage = sovrinDID.signMessage(message, signKey, verifyKey);;

		```
		### sovrinDID.verifySignedMessage(signedMessage, verifyKey)
		Verifies that the given message has been signed by the possessor of the given verifyKey.

		* The signedMessage should be what is returned from the `signMessage(message, signKey, verifyKey)` method
		* The verifyKey should be the verifyKey given from the `gen()` or `fromSeed(seed)` methods

		Returns `true` if the message was signed by the owner of the verifyKey `false` otherwise.

		Example:
		```js
		var sovrin = sovrinDID.gen();
		var sovrin2 = sovrinDID.gen();

		var signKey = sovrin.secret.signKey;
		var verifyKey = sovrin.verifyKey;
		var verifyKey2 = sovrin2.verifyKey;

		var message = "Hello World!!";

		var signedMessage = sovrinDID.signMessage(message, signKey, verifyKey);

		console.log(sovrinDID.verifySignedMessage(signedMessage, verifyKey));
		console.log(sovrinDID.verifySignedMessage(signedMessage, verifyKey2))
		```

		Output:
		```
		true
		false
		```
