Supported Payment Processors

[Upperholme]

Not a feature request, rather just seeking clarification. Does this plugin support Caldera's Paypal express processor, enabling memberships tote bought and the transaction recorded in Civi? I ask as the available information sort of implies that all of Caldera's payment add-ons are supported, but there's nothing explicitly on this that I can find. And the changeling makes reference to just Stripe and (I think) authorize.net support in an earlier version.

Thanks for a great plugin.
