How to C#: add a settings file to your Console application

### Guide ###
Simply follow these steps to load your appsettings into a class for easy use.
-  Add the references above to the project
-  Add a new class called `ApiSettings.cs`

public class ApiSettings
{
    public string TwitterApiKey { get; set; }
    public string TwitterApiSecret { get; set; }
    public string BearerToken { get; set; }
}

-  Add a new class called `Startup.cs`

        IConfiguration config = builder.Build();

        ApiSettings = config.GetSection("ApiSettings").Get<ApiSettings>();

    }

    public ApiSettings ApiSettings { get; private set; }
}

- Add your `appsettings.json` with content similar to something like this:

- Right click on the file `appsettings.json` and set the copy output to `Copy always`

-  Make sure the fields in the section 'ApiSettings' match your ApiSettings.cs class.

- Go back to your Program.cs file and add the following line:
`var startup = new Startup();`
- We can now use the values in the ApiSettings section of our appsettings. You can try it out with the following code.
