Counts the items.

This function is an aggregation function that counts the number of times it is evaluated per group by context. It is useful in a GROUP BY clause to count the number of items in each group.

You can also use it in a regular query to produce a row count. NOTE: When used in this way it only counts the total number of rows that are actually evaluated (i.e. not filtered out) due to the lazy evaluation property of VQL columns.
