Detailed Description

A temporary computational field.

A ScratchField is similar to a Field in usage, but is temporary in nature. It is used as a scratch buffer to compute intermediate quantities. However, unlike fields these don't have multiple states, and cannot survive across a regrid. By default, FieldRepo returns a unique pointer to this instance and it is not safe to hold this pointer across timesteps.

At present, ScratchField cannot be used for I/O and/or post-processing utilities.
