A JoinRole is a simple ProxyRole that concatenates other roles.
In the following example, the fullName role is computed by the concatenation of the firstName role and the lastName role separated by a space :
SortFilterProxyModel {
   sourceModel: contactModel
   proxyRoles: JoinRole {
       name: "fullName"
       roleNames: ["firstName", "lastName"]
  }
}
This property holds the separator that is used to join the roles specified in roleNames.
By default, it's a space.
