Decorates another atom and transforms its output to another type.
An Atom is a thin wrapper around javascript.
The wrapped script can return a value or be a statement. The Atom can supply positional
arguments to pass to the wrapped script. The Atom knows how to transform the result of the
evaluation of the script into a higher level object.
