More Functional

Changes to Rummage as whole:

• This release is to illustrate the actual behavior of Rummage, which is functional:

  • Instead of EctoSchema.rummage(query, rummage), call Rummage.Ecto.rummage(query, rummage)

• Default Hooks can handle any number of associations.

Changes to complexity:

• Hooks are more independent of each other due to a newly introduced before_hook feature. This
  allows us to format rummage_params based on what a hook is expecting and keep the code clean.

In Progress:

• A CustomHook with key-set pagination based on this link.
