Add example : how to extract Props / State interface from react component using compiler API

Hello.
I have this sources

import * as React from 'react';

export interface MyComponentProps{
    prop1: number;
    prop2: string;
}
/**
* descriptions for component
*/
export  class MyComponent extends React.Component<MyComponentProps,{}>{
   render(){
     return(
       <div>
       </div>
     );
   }
}

I use docgen from this wiki example

this is output

[
    {
        "name": "MyComponent",
        "documentation": "descriptions for component",
        "type": "typeof MyComponent",
        "constructors": [
            {
                "paramters": [],
                "returnType": "MyComponent",
                "documentation": ""
            }
        ]
    }
]

I want to extend this output by type of first generic passed to react.component.

How to extract generic type passed to parent class?
Thank you!

Start with the linked TypeScript Compiler API wiki example and the shown React.Component generic usage. Add a wiki example demonstrating extraction of the first generic type and showing the expected output for MyComponent; done means the example clearly answers the requested Props/State extraction.
