Overview

Defines a top-level key and the associated transformers for deriving the final value to set the key to. The transformers that can be passed in can be any Realize::Transformers subclasses. For more information, see the Realize library at: github.com/bluemarblepayroll/realize

Note that if explicit: true is set then no transformers will be automatically injected. If explicit is not true (default) then it will have a resolve job automatically injected in the beginning of the pipeline. This is the observed default behavior, with the exception having to be initially cross-mapped using a custom resolve transformation.
