// Description:
// Helper class supplying useful logging functions to the providers in the layer
//
//
//  This is a 3-plane comms layer implementation example, which has been customised to be a test layer which gobbles and releases ESOCK MBUFs.
//  The MBuf gobbling functionality can be disabled by undefining the macro SYMBIAN_COMMSFW_MBUF_GOBBLER which is specified in mbufgobblerproviders.mmp.
//  When SYMBIAN_COMMSFW_MBUF_GOBBLER is undefined, the source code specified by mbufgobblerproviders.mmp becomes a pass through layer i.e. it passes the data
//  through to the layer above or below without altering it. This makes it useful as a starting point for implementing your own layers / providers;
//  useful documentation on how to customise your own passthrough layer can be found in ..\docs\MbufGobblerLayer.doc
//
