// Declaration of the class for the network instance provider for IntelMobile.  It 
// supports all types of devices according to specification.
//
// It's only job is to create InstanceObjects.  Including the base header for
// network instance providers and implementing the functions are all that's
// necessary.
//
// The heart of creation is done in the following files:
//	instance_NetworkAdapterInstanctObject
//	instance_RadioAdapterInstanctObject
//	instance_WiredAdapterInstanctObject
//	instance_Protocol802_11InstanctObject
//	instance_Protocol802_3InstanctObject
