* The ProtocolStack configuration is a list of key names for the components
* in the stack. It is an in-order list of the components to configure in the
* stack.
*
* @code
* {
* // Configure a stack with {APIConnector,TLVCodec,MetisConnector}
*
* stackConfig = ccnxStackConfig_Create();
* connConfig = ccnxConnectionConfig_Create();
*
* apiConnector_ProtocolStackConfig(stackConfig);
