IAssertionGroup

interface IAssertionGroup : IAssertion

The base interface for IAssertion groups, providing a default implementation for IAssertion.holds which returns true if all its assertions hold.

assertions	`abstract val assertions: List<IAssertion>` The assertions of this group, which are defined for subject.
name	`abstract val name: ITranslatable` The name of the group.
subject	`abstract val subject: Any` The subject for which the assertions are defined.
type	`abstract val type: IAssertionGroupType` The type of the group, e.g. RootAssertionGroupType.

open fun holds(): <ERROR CLASS>

Holds if all its assertions hold.

AssertionGroup	`data class AssertionGroup : IAssertionGroup` Represents a group of IAssertions -- it has a certain type, a name, a subject and of course assertions.
EmptyNameAndSubjectAssertionGroup	`abstract class EmptyNameAndSubjectAssertionGroup : IAssertionGroup` Represents a base class for IAssertionGroups which have an empty name and subject.
FixHoldsAssertionGroup	`data class FixHoldsAssertionGroup : IAssertionGroup` Represents a group of IAssertions -- it has a certain type, a name, a subject, assertions and a fixed value for holds which does not depend on assertions (usually indirectly).
LazyThreadUnsafeAssertionGroup	`class LazyThreadUnsafeAssertionGroup : IAssertionGroup` Represents an IAssertionGroup which is evaluated lazily where the lazy loading is not thread safe.
