func CompressUpdates

func CompressUpdates(changes []*Package) (update []*Update)

CompressUpdates detects updates of the same source package to the same version and considers them related. This is useful for display of changes to the user. e.g an update of 29 packages is actually just 5 different sets of updates, where each has a bunch of related packages compiled from the same source package update.
