replace associations mechanism

[lanej]

is currently very clunky.

Instead of modeling associations as instance variables, they could simply be referred do as attributes. There would be a belongs_to and a has_many.

• has_many: would likely require a block form argument yielding a scoped collection that would be stored in the attribute.
• belongs_to: should be a simple as declaring the class and making cistern do the leg work.

Side effects:

• aping objects would also print nested objects within. This would also force load any association not already loaded.
• sideloading would become feasible from the model api.

cistern support for associations is available in 2.6
