/**
 * @class CE_ARGV
 *
 * @brief This class is to hash input parameters, argc and argv, for WinCE platform.
 *
 * Since WinCE only supports wchar_t as an input from OS, some implementation detail,
 * especially for CORBA spec, will not support wchar_t (wchar_t) type parameter.
 * Moreover, WinCE's input parameter type is totally different than any other OS;
 * all command line parameters will be stored in a single wide-character string with
 * each unit parameter divided by blank space, and it does not provide the name of
 * executable (generally known as argv[0]).
 * This class is to convert CE's command line parameters and simulate as in the same
 * manner as other general platforms, adding 'root' as a first argc, which is for the
 * name of executable in other OS.
