Several fixes regarding to default node configuration.
Performance improvements.
Code style improvements.

If you would like to test the new Scalenet network using our C# API, you can follow these simple steps:

> "Hello, Scalenet"

Using this library is very simple, since Knuth provides a NuGet package.

1. Create a new C# console project:

$ mkdir HelloScalenet
$ cd HelloScalenet
$ dotnet new console

2. Add a reference to our C# API package:

$ dotnet add package kth-bch

3. Edit `Program.cs` and write some code:

using System;
using System.Threading.Tasks;
using Knuth;

namespace HelloScalenet {
    public class Program {
        private static bool running_;

        static async Task Main(string[] args) {
            Console.CancelKeyPress += OnSigInterrupt;

            var config = Knuth.Config.Settings.GetDefault(NetworkType.Scalenet);
            using (var node = new Knuth.Node(config)) {
                await node.LaunchAsync();
                Console.WriteLine("Knuth node has been launched.");
                running_ = true;

                var height = await node.Chain.GetLastHeightAsync();
                Console.WriteLine($"Current height in local copy: {height.Result}");

                if (await DownloadSomeBlocks(node)) {
                    Console.WriteLine("Bitcoin Cash has been created!");
                }
            }
            Console.WriteLine("Good bye!");
        }

        private static async Task<bool> DownloadSomeBlocks(Node node) {
            UInt64 height = 12000;
            while (running_) {
                var res = await node.Chain.GetLastHeightAsync();
                if (res.Result >= height) return true;
                await Task.Delay(10000);
            }
            return false;
        }

        private static void OnSigInterrupt(object sender, ConsoleCancelEventArgs args) {
            Console.WriteLine("Stop signal detected.");
            args.Cancel = true;
            running_ = false;
        }
    }
}
