Get aggregated performance statistics for a single form within a date range. The response contains
statistics (totals across all devices) and statisticsByDevice, the same counters split into the
desktop, mobile, and tablet buckets. Device buckets with no activity in the range are omitted.

Metrics:

• views — times the form was displayed to a visitor. This is the denominator for conversion rates.
• interactions — views where the visitor engaged with the form (for example focusing a field or
  clicking a button) without necessarily completing it.
• submits — times the form was successfully submitted.
• signups — contacts gained from those submissions. Signups can differ from submits: a submission by an
  already known contact, or a multi-step form counted once per step reached, means the two counters are
  related but not interchangeable.

Each metric is a subset of the previous one in the funnel: views ≥ interactions ≥ submits.

The date range is required and is interpreted in the brand's timezone. Use
GET /forms/{formID}/report/periodic instead when a time series (per hour, day, week, month, or year) is
needed rather than a single total.
