// Creates a policy template. A template can use placeholders for the principal
// and resource. A template must be instantiated into a policy by associating it
// with specific principals and resources to use for the placeholders. That
// instantiated policy can then be considered in authorization decisions. The
// instantiated policy works identically to any other policy, except that it is
// dynamically linked to the template. If the template changes, then any policies
// that are linked to that template are immediately updated as well.
