Detailed Description

template<class Class, class ValueType = InstanceIdDefaultValueType>
class InstanceId< Class, ValueType >

Identifier for class instances

• unique IDs for a large number of concurrent instances, but may wrap;
• useful for debugging and insecure request/response matching;
• sequential IDs within a class except when wrapping;
• always positive IDs. TODO: add creation/destruction debugging?
