Enforce associations (and may be coercion/validation) definitions

#57

There seems to be a problem with associations at least (on second console load):

User = Meta.new do
     has_many :items
end
    # ==> User
Item = Meta.new
    # ==> Item
User.document
User.document

- State changed from new to resolved
we had major serialization problems in storage... preliminary fix has been developed (though we still need to refactor serialization)
