title: Tokenize bank info with Stripe iOS SDK
body: <p>Using the UI components in the Stripe iOS SDK, I can easily generate a token/Stripe Source ID client side to securely pass credit card info to the server. I cannot seem to find a similar tokenization feature for bank account info. I can gather bank info client side with STPBankAccountParams, but is there a way to tokenize this info to then pass to the server?</p>
