// The following templates are used to quickly and easily create a class that
// wraps around a simple type (such as int) and can be put into TwoWayList or
// (In)EfficientMap.
// The "Swapify" template attaches only a Swap operation (so a simple type can
// be used with TwoWayList).

// SPECIAL NOTE: ONLY USE THESE TEMPLATES WITH SIMPLE TYPES (int, double, etc.)
// These templates use the = operation, so they are only safe with such types.
// If the type is more complicated, then create a class with Swap and IsEqual.
