/** 

Abstract WAP Push log access interface: logging is primarily for debugging.

The standard Symbian OS WAP Push watcher component writes to a log at c:\\logs\\watcher\\watcher.txt 

if the c:\\logs\\watcher\\ directory exists. It supplies this interface to push 

plug-ins through CPushHandlerBase::SetLogger(). The plug-in can then call 

the interface's functions to add its own messages to the log.
