experience builder widget samples

Attempt at creating some Experience Builder widgets.

As-is, none of these are ready to simply be plugged in.

Lat-long

Just the UI, nothing working in the back end

Works, but the UI needs to be cleaned up This is a good proof of concept of making widgets from Esri JS 4.X API work inside XB

Create a new widget in client\your-extensions\widgets\your widget (can copy simple)
- Inside manifest.json update the name to match the folder name
- Add the jimu-arcgis as a dependency
npm start in client
From XB, create a new Experience, add the new widget. Save
To focus on widget, copy server\src\public\apps\X\config.json to client\dist\experience\configs\config.json
open localhost:3001/experience?config=configs/config.json

match any properties the config.json and the src\config.ts >> export interface Config { **** }

in manifest.json add new locale for language
create src\runtime\translations\default.ts >> export default { varName: "String" }
create src\runtime\translations\fr.js >> define ({ varName: "French String" })
in widget.tsx >> import defaultMessages from "./translations/default.ts";
helper function:

   return this.props.intl 
    ? this.props.intl.formatMessage({
	  id:id,
	  defeaultMessage: defaultMessages[id],
	  })
	  : id;
};
