// - It is possible for the active campaign to be automatically
// stopped, as it has a valid end date. (No limitations are
// applied to those campaigns tested, as the ME may not have
// run for a while, and if so, even campaigns with an end date
// of many, many weeks ago should be tested to ensure they are
// [belatedly] halted.)
// - It is possible for the active campaign to be automatically
// stopped, as it has at leaast one lifetime target that could
// have been reached.
//
// The campaign is INACTIVE and:
// - The start date stored for the campaign is not null; and
// - The weight is greater than zero; and
// - The end date stored for the campaign is either null, or is
// greater than "today" less one day.

// - The campaign is not in a permanently inactive state, as a
// result of the weight being less then one, which means that
// it cannot be activated.
// - The test to start the campaign is unlikely to fail on account
// of the end date. (Inactive campaigns with start dates may have
// passed the start date, but they may also have passed the end
// date - unfortunately, because the dates are not stored in UTC,
// it's not possible to know exactly which campaigns have passed
// the end date or not, until the values are converted to UTC based
// on the Advertiser Account timezone preference - so it's necessary
// to get some campaigns that might be passed the end date, and do
// the converstion to UTC and test to check.)
