has_many, through

[swilliams]

Need to enable has_many through relationships. Example

class Resource
end

class Role
  has_many :resources
end

class User
  has_many :roles
  has_many :resources, through: :roles
end

This means that User instances have a list of Resources that are provided by their Roles list.

As of now this can be done by 'plucking' the Resources property from each Role on a User. However, this would also result in an HTTP call for each Role, which would be very slow. Consider creating an :include functionality first.
