A class derived from RedundancyGroup indicating that one or more of the aggregated elements can be spared. (The actual Spares are defined using the ActsAsSpare association.) An example is the use of redundant NICs in a ComputerSystem - where one NIC is primary and the other is Spare. The 'primary' NIC would be a member of the SpareGroup (associated using the RedundancyComponent class) and the 'other' NIC would be associated using the ActsAsSpare relationship.
