Create Divison class

ODDB::Divison class include SequenceObserver

ch.oddb> Divison.new.sequences
-> []
ch.oddb> sequences.values.first.division.nil?
-> true

Sequence Model

I created updation/creation by pointer.
Sequence model has to have following methods.

create_division

    def create_division
      div = Division.new
      div.add_sequence self
      @division = div 
      div 
    end

division=

    def division=(division)
      super(division)
      @division = replace_observer(@division, division)
    end

And doesn't have to implement.

divison

  def division
    @division || Division.new
  end

Assign same Object

Sequences can pointer to same Division Object. (like patinfo,fachinfo)
