Returns stats for the specified custom date range.
Returns stats for the specified custom date range. Both parameters can be either an object containing year, month, and day fields, or an 8-digit string in
YYYYMMDD
form. For instance,
March 24th, 2013
is represented as either
{year: 2013, month: 3, day: 24}
or
"20130324"
. The date range is inclusive on both ends, so
forDateRange("20130324", "20130324")
defines a range of a single day.
