/**
 * Class user, instances of which represent a specific lti user in the tool.
 *
 * A user is always associated with a resource, as lti users cannot exist without a tool-published-resource. A user will
 * always come from either:
 * - a resource link launch or
 * - a membership sync
 * Both of which required a published resource.
 *
 * Additionally, a user may be associated with a given resource_link instance, to signify that the user originated from
 * that resource_link. If a user is not associated with a resource_link, such as when creating a user during a member
 * sync, that param is nullable. This can be achieved via the factory method user::create_from_resource_link() or set
 * after instantiation via the user::set_resource_link_id() method.
