Dwolla Merchant Processor

[michaelblinn]

To save on transaction costs, giv2giv uses dwolla.com for its transaction processing.

Dwolla has an official ruby wrapper for its API at https://github.com/Dwolla/dwolla-ruby

Among other things, it allows for:

• creating donors' accounts
• requesting funds
• initiating transfers
• making grants to charities via email address
• webhooks upon transaction status update
• detailed transaction information

This issue entails Dwolla integration for the movement of all funds throughout the entire giv2giv platform.

This functionality is tightly coupled with funds tracking.

See funds_tracking.rb for neo4j-integration functions

Since we are considering having more than one payment method in the long term (ie PayPal etal) we should work this in such a way as to remain the authority on the data. Don't depend on Dwolla to store all the account information.
