Add createCard to the list on generally available actions

[eileenmcnaughton]

I'm proposing we add createCard to the list of actions as it is a key action IMHO.

The general case is that credit card details are passed in and a cardReference is returned (available by getCardReference) this can generally be used instead of credit card details in later requests.

I'm struggling a little with the Paypal Rest integration on this front as it's possible to 'create a card' when there is no card details (in the Paypal button implementation a the person is redirected to Paypal & returns with a token that if functionally equivalent to one the generic concept of 'createCard' so I though at least adding the concept into the readme is a step forwards.

I think we can do this. It seems also fetchIssuers is mssing here.

I don't even know what fetchIssuers does :-)

Other gateways share PayPal's concept of a "card token" as being a generic token that gives the application the ability to use some pre-authorised payment method, whether a card, bank account, direct debit, giropay etc.

The issuers I think is a little more tricky. Issuers are about who issues a payment method, and I always thought it only makes sense in the context of a payment method, but I am not entirely sure. For example Adyen can provide a list of card types available, and for some of those card types a list of issuers. The shop can then choose which issuers to use. It may accept Visa from Bank A, or Mastercard from banks A or B, but not C. It's more common in the EC outside of the UK, so not something I am entirely familiar with, but hopefully that should give you a lead.

We use @judgej card token implementation for different drivers, e.g.

• GiroCheckout: https://github.com/academe/omnipay-girocheckout#create-a-reusable-card-reference
• Datatrans: https://github.com/academe/omnipay-datatrans#getting-a-card-reference

Is is worth adding updateCard and deleteCard to the docs here?
