Abstract BusinessObject for StromDAO Energy Blockchain. Abstraction layer between blockchain technology and business logic providing energy market related entities and use cases.

/**
 * StromDAO Business Object: DirectConnection
 * =========================================
 * Directly connect for Energy delivery to an account within StromDAO Energy Blockchain.
 * 
 * DirectCharging gets used together with DirectConnections.
 * 
 * In theory account A and account B are exchanging energy metered by meter_point C
 * 
 * DirectCharging takes several DirectConnections and runs charging as soon as method chargeAll is called.
