* This is a helper class to construct a string representing the services accessible by an AccountSAS. Setting a value
* to true means that any SAS which uses these permissions will grant access to that service. Once all the
* values are set, this should be serialized with toString and set as the services field on an
* {@link AccountSASSignatureValues} object. It is possible to construct the services string without this class, but
