Archttp - Fast and easy to use web framework.

[zoujiaqing]

Hi, everybody.

The epidemic in China is serious. I am in home quarantine in 
Shanghai.

I used to write a lot of frameworks. But they are huge and 
difficult to use.

I've always wanted to design a lightweight Web framework that is 
easy to use and has good performance. These days I finally write 
a version. This version currently runs well on Linux and macOS. 
We haven't had time to test it on Windows yet.

## Sample code:
```D
import archttp;

void main()
{
     auto app = new Archttp;

     app.Bind(8080);

     app.Get("/", (context) {
         auto response = context.response();
         response.body("Hello Archttp");
     });

     app.Get("/json", (context) {
         import std.json;

         auto response = context.response();
         auto j = JSONValue( ["message" : "Hello, World!"] );

         response.json(j);
     });

     app.Get("/user/{id:\\d+}", (context) {
         auto request = context.request();
         auto response = context.response();
         response.body("User id: " ~ request.parameters["id"]);
     });

     app.Get("/blog/{name}", (context) {
         auto request = context.request();
         auto response = context.response();
         response.body("Username: " ~ request.parameters["name"]);
     });

     app.Post("/upload", (context) {
         auto response = context.response();
         response.body("Using post method!");
     });

     app.Run();
}

```

The project relies on 'nbuff' and 'httparsed', which provide very 
powerful support for 'Archttp'.

  ** Thanks to 'ikod' and 'Tchaloupka'.**

Be aware that there will be many changes and tweaks to the API in 
the future. It's not a stable version yet.

The current project supports HTTP 1.1 request processing. And a 
good built-in routing module.
