Atoms and Tasks
---------------

An atom is the smallest unit in taskflow which acts as the base for other
classes. Atoms have a name and a version (if applicable).  Atom are expected 
to name desired input values (requirements) and name outputs (provided
values), see :doc:`arguments_and_results` page for complete reference
about it.

A task (derived from an atom) is the smallest possible unit of work that can
have a execute & rollback sequence associated with it.
