val AssertionBuilder.fixedClaimGroup: FixedClaimAssertionGroupTypeOption(source)
Builder to create an AssertionGroup whose AssertionGroup.holds is fixed (not determined based on its AssertionGroup.assertions).
The intended use case is if all AssertionGroup.assertions are AssertionGroups with an
ExplanatoryAssertionGroupType. Such groups always return
true for AssertionGroup.holds but you might want to
explain a complex failing assertion with those groups. In such a use case this builder is your choice.
