/*
 * ============================
 * = POLICIES IMPLEMENTATIONS =
 * ============================
 *
 * The Policies object below is where the implementation for each policy
 * happens. An object for each policy should be defined, containing
 * callback functions that will be called by the engine.
 *
 * See the _callbacks object in EnterprisePolicies.js for the list of
 * possible callbacks and an explanation of each.
 *
 * Each callback will be called with two parameters:
 * - manager
 *   This is the EnterprisePoliciesManager singleton object from
 *   EnterprisePolicies.js
 *
 * - param
 *   The parameter defined for this policy in policies-schema.json.
 *   It will be different for each policy. It could be a boolean,
 *   a string, an array or a complex object. All parameters have
 *   been validated according to the schema, and no unknown
 *   properties will be present on them.
 *
 * The callbacks will be bound to their parent policy object.
