I'm not sure I understand.  I would like to have access to both class and
instance methods.  Basically some of my code looks like this.

day = A.new(1.days.ago, Time.now)
hour = A.new(1.hour.ago, Time.now)

Then I would also like to be able to use arbitrary starting and ending
ranges with the class method, without the need to create an instance.

total_incoming = A.total_incoming(1.year.ago, Time.now)

If you do want to do this, you can automate it by creating
