    # Helper for model classes.
    # Allows for convenient instantiation of current athlete.
    # This is completely agnostic to class type, it can be a DB model, a PORO, etc.
    # 
    # Usage:
    # 
    #     class Account < ApplicationRecord
    #       include Strava.model as: :athlete, via: :token, id: :strava_id
    #     end
    #     ca = Account.find(1).athlete # => Strava::Athlete
    # 
    # Can also perform lookup through another method:
    #
    #     class User < ApplicationRecord
    #       has_one :account
    #       include Strava.model as: :athlete, via: 'account.token', id: 'account.strava_id'
    #     end
    # 
    # @param as [Symbol] method to define to return current athlete
    # @param via [Symbol, String] method to lookup access token
    # @param id [Symbol, String] method to lookup Strava ID
    # @return [Module] module to be included in the calling class
