Focus Functions

Focus functions define transformations applied to individual unit estimates. They consist of two components:

1. Focus Function: Maps estimates to a scalar parameter of interest.

2. Gradient: Computes derivatives for optimization.

Available focus functions classes:

Class	Description
BaseFocusFunction	Abstract base class. Subclass and implement focus_function() and gradient().
InlineFocusFunction	Convenience class for creating focus functions from callables.
