Detailed Description

Protocol for implicit source terms.

A struct conforming to this protocol must also conform to protocols::StaticReturnApplyable. The return_tags of this struct must be a list of Tags::Source<T> for every tensor T in the implicit sector.

The argument_tags must not include compute items depending on tensors in the implicit sector.
