Comment 1 for bug 1840782

Here's a branch:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1840782-date-time-native-widgets

From the commit: ---

Migrate <eg-date-select> implementation from ng-bootstrap to the browser-native <input type="date"/> element.

Create a DateUtil class to package some common date transforms, etc.

'DOB' handling in FormatService leverages the new DateUtil class for generating a local date from Y/M/D and does so any time a simple Y/M/D value is passed, instead of limiting to 'DOB' values.

Sandbox example expanded to demonstrate date clearing and improve layout.
