signac-dashboard init

[atravitz]

Feature description

It would be nice to have something analogous to flow init, as a starting point for modifying things. e.g. I wanted to just change the titles, but then running python dashboard.py meant that I no longer had the default modules showing. It'd be much easier to have the default settings generated with an init call that users can then build on.

Proposed solution

signac-dasboard init that generates a dashboard.py script with all the default modules

@atravitz I definitely want to add this feature. What modules would you include by default? (list of modules for reference)
