//  Class:      CFileEnumurate
//
//  Purpose:    encapsulation of File enumeration, this class takes
//              a path/filename with wildcards and a depth option,
//              and provides init and next methods to allow iteration
//              thru all the files specfied by the input path/filename and
//              depth option
//
