Description: Square's e-commerce API support added to Active Merchant. (This depends on core active merchant, so it can coexist peacefully with upstream changes there. Not merged into Active Merchant for reasons as described here https://github.com/activemerchant/active_merchant/pull/2242)  See example below, and our blog post: https://medium.com/square-corner-blog/activemerchantsquare-for-squares-e-commerce-api-111ea63e530a
