/**

Symbian CConsoleBase implementation that uses a Win32 console.

It supports all of the CConsoleBase API. It also supports piping of test written

to the console into a Win32 file or process, if the emulator is launched from a

script in an appropriate manner.

More specifally:

- Redirection to a file: i.e. if the emulator is launched the emulator STDOUT

  piped to a file, data written to this console will end up in that file

- Attaching to the console of the parent process: i.e. when the emulator is

  launched from a windows Command Prompt box, output will appear there

- Creating a new console, if the emulator is lauched from a process with no

  console. This will happen if the emulator is launched from an IDE.

Piping into the emulator process via this console is as yet untested.
