* dialog with a single argument - a reference to an object with .providerNum
* and .userAgreed properties. This code displays the dialog for the provider
* as dictated by .providerNum and loads the policy. When that load finishes,
* the OK button is enabled and the user can either accept or decline the
* agreement (a choice which is communicated by setting .userAgreed to true if
* the user did indeed agree).
