/* somewhere in your Core.CQRS */

// Base class for all ES-based aggregate command handling components; 
// 
// NOTE: "Component" is a logical grouping of message handlers by function
//             They provide good place to encapsulate chaining of cross-cutting concerns 
//             into a pipeline, providing simplified helper methods for registration of message handlers
//
// Components are similar to Services, thus they only contain handlers of single type (ie Command Handlers only)
// Components operate on envelope (infrastructure) level
