New feature for API usage based on webtask model

[facundocabrera]

Hey all,

I was checking https://webtask.io/docs/model and I found really interesting the idea of provide a simple API like this project. Imagine to be able to add code other than simple HAR compliant data.

return function (context, req, res) {
    res.writeHead(200, { 'Content-Type': 'text/html '});
    res.end('<h1>Hello, world!</h1>');
}        

Pros:

1. Simple API.
2. Extensible to add custom behaviors using express/node modules.
3. Not require to read any documentation to start other than simple javascript code.
4. Some of the current issue could be addressed using this approach before make them officially available inside mockbin.

I'm pretty new using mockbin, but feels this could be a really nice behavior to be added.

Thanks in advance
