/**
 * Find all method or fields that are candidates for providing a Context.
 * There can be various choices amongst this class or its super classes.

 * The best ever choice is to find a method with no argument that returns a Context.

 * desirable since we can't generate these arguments automatically.
 *
 * Methods and fields from supertypes are ignored if they are private.
 *
 * The rating is reversed: the lowest rating integer is used for the best candidate.
