Add USNG Overlay Capability in All Apps

[PaulDoherty2]

The Web AppBuilder Team has done a fantastic job of supporting the US National Grid with the Grid Overlay, Grid Reference, Coordinate Conversion, etc. but this is a capability that needs to be pervasive throughout all apps.

Audience: All First Responders and Emergency Managers

Problem: US National Grid is the official coordinate notation for points and areas for search and rescue and emergency management.

Solution: Provide Grid Overlay capabilities in the following apps 

- Operations Dashboard Operations Dashboard for ArcGIS‌

- Explorer for ArcGIS Explorer for ArcGIS‌

- Collector for ArcGIS Collector for ArcGIS‌

- Survey123 for ArcGIS Survey123 for ArcGIS‌

Closing due to inactivity and low support from the community. There also appears to be a few ideas here. To get more support, it might make sense to submit them individually and tailor them specifically to a Dashboards.
