I have added a fairly important collection of methods with this commit.

When I release the library - it's usually aligned to whatever the current schema is. But this can cause problems, if connecting to external servers that are older then what the schema is during release time of the lib (the lib is somewhat bias to the embedded runtime)

1 example is healing the network, the commands have been renamed in new schemas (I haven't yet).

But this commit allows to (during runtime).

• Add new methods
• Restore renamed methods

This is extremely handy to support older servers (that may use old method names), or utilise newer methods since release time.
Here is how.

var MyMethod = MethodFactory.CreateCLASS(_Driver, "node.unimplmented_method_example", typeof(MyMappedClass), "result.some.result.path");

Dictionary<string, object> Parameters = new Dictionary<string, object>();
Parameters.Add("nodeId",46)
MyMethod.Invoke(Parameters).ContinueWith((R) =>
{
   if (R.Result.Success)
   {
       MyMappedClass MyClass = R.Result.ResultPayload as MyMappedClass;
   }
});

The methods are in the MethodFactory class
I will be merging this PR into the V4 PR/Branch soon
