Remarks

Use binary search to find the first and last element inside a TPagedArray that overlaps a given input interval. This requires the elements in the array to be sorted by the value returned from the Projection. Example usage for Timeline events would require a projection that returns Item.StartTime and the resulting range.Min will point to the last element where Item.End > StartTime and range.Max to the last element where Item.StartTime < EndTime.
