startGroup property
If k metrics were requested, then the response will contain some data-dependent multiple of k columns in the report.
E.g., if you pivoted on the dimension ga:browser then you'd get k
columns for "Firefox", k columns for "IE", k columns for "Chrome", etc.
The ordering of the groups of columns is determined by descending order of
"total" for the first of the k values. Ties are broken by lexicographic
ordering of the first pivot dimension, then lexicographic ordering of the
second pivot dimension, and so on. E.g., if the totals for the first value
for Firefox, IE, and Chrome were 8, 2, 8, respectively, the order of
columns would be Chrome, Firefox, IE. The following let you choose which
of the groups of k columns are included in the response.
