Metrics Mapbox Groups maps: Add time filter for start date.

[corsacca]

Could a time filter be added to that page that filters groups based on church start date? some logic parameters I thought about:

• load the initial page with the filter off
• only base the filter on the church start date field of a group
• if user adds just the filter start date and no end date -> re-query groups with that church start date or after
• if user adds no filter end date -> re-query groups with the church start date or after with no limits
• if user also adds a filter end date -> re-query groups with church start date that falls within the filter start and end date parameters.

It might be easier to use the existing date filter from other metrics areas.

We might consider choosing any date field instead of just group start date.

What about create a filter for any field?
