UX Investigate and evaluate sharing feature

[emettely]

Is your feature request related to a problem? Please describe.
Not a problem so to speak - but there's been quite a lot of chatter from UX interviews that they'd want a more collaborative way to work. One of the suggested ways was to "Share". We want to understand what the size of the demand is and what it solves.

Describe the solution you'd like
A decision on the sharing feature.

Describe alternatives you've considered
The alternative is not allow users to directly share in DPE's UI, but they'll share the files exported from DPE.
