Need "Share Current Map View" widget for Web AppBuilder

Idea created by geonb_bernie on Mar 3, 2015
    One of the best ways to get your webmap noticed and to increase visitors is to make it really easy for visitors to share your map.  Now that we have new URL parameter capabilities in Web AppBuilder 3.7 that allow the center and scale of the map to be defined we need somebody to build a widget for sharing the current map view.  It could use the ubiquitous "Share This" icon:
    'Share This' icon
    It sounds really simple.  All you have to do is append "&center=<longitude>,<latitude>&scale=<scale>" to the URL and then run it through a URL shortening service.  If I could program in JavaScript I would do it myself ;-) but I can barely write python scripts.
