module UserAbilities
# Should be included into whatever class represents users in an app.
# Provides methods like `can_update?(resource)`
# Exactly which methods get defined is determined from `config.abilities`;
# the module is evaluated after any user-supplied config block is run
# in order to make that possible.
# All delegate to corresponding methods on the resource.
