 /**
  * This class will take an entity of either site, service group, NGI or Project.
  * It will then get the roles from the entity
  * and then get the users for each of those roles. Then using the authorizeAction function for the correct entity type it will
  * ascertain if a given user has the permission to grant a role. If they do there email address is added to an array. This array
  * of email addresses will then be sent a notification that they have a pending role request they can approve.
  *
  * If a site or NGI has no users with roles attached to it due to being newly created then this method will get the parent NGI and
  * send an email to those users to approve. It does this by passing the parent entity back into this method recursively.
