Detailed Description

Transaction: A wrapper over a Block that defines the communication of a block with a Container.

This minimalist struc is the only block wrapper across anything. Anything is: file I/O, http client CRUD, http server GET and PUT, shell commands, Volatile, Persisted and Index objects (an stdlib map that serializes to and from a block).

Transaction allocation is only handled by the owner, a Container or descendant.
