UPS OAuth token and Commercial/Residential Addresses

[owi2000]

With the UPS change to use OAuth tokens for their APIs, I'm having trouble with setting the residential flag for delivery addresses. UPS offers the Address Validation API free to it's customers that we've been using to get the residential/commercial status of addresses. The problem is that ShippingRates neither has the AddressValidation API included in it, nor does not allow access to get the OAuth token (it's an internal class). This means in order to access this API, I would need to generate my own token, even though the token acquired using ShippingRates would be valid for any UPS API requests for several hours. (I would prefer not to have to do this, since the goal of using ShippingRates is to simplify our interactions with the different carriers.)

I would like to see either the ShippingRates utilizing the AddressValidation API (so the dev doesn't need to set the Residential flag in requests) or the token be made available to the dev (this would necessarily include the requirement for methods to obtain a new token automatically in the event the current one expired).

I should note that the FedEx also has an Address Validation API, so this could also apply to FedEx. The rates for both services is dependent upon whether or not the address is a residential address, so including these API's in ShippingRates would make sense.

Sounds like a good idea! Will take this in work.
