//***********************************************
// Simple Message Filer (Version1)
// This implementation introduces the message and messageFolder objects
// Uses Message Class Objects (message.h)
// Each Message is stored in a separate file
// Each Message Folder contains a file which contains Message Header for each Message in the folder
// The Message Folder is also encapsulated in a class. (messageFolder.h)
//		FILE IO:
// terminal input and output uses c++'s cin and cout operators
// However for file I/O we use win32 file routines
// even though c++ or c's file I/O may be more preferable because of
// its portability. We are here to learn windowsNT not c++
//		USER INTERFACE:
//	It's single character command driven with integer message numbers as appropriate.
//	Accepts both upper and lower case commands.
//			L:	List the messages currently available
//			A:	Adds a new message to the end of the list
//			D #: Deletes message # from list (actually just marks it for deletion)
//			S #: shows message #
//			I folderName: inputs message list in folderName
//			O [folderName]:	outputs message to folderName(default is input folderName)
//			H:	prints commands (also ?) will work
//			Q: quit program
//	There can be only one blank between I or O and the folderName ( pretty ugly huh?)
//	Messages are arbitrarily numbered from 1 to the last message
//	Messages consist of a topic( up to 50 characters) and text (up to 300)
//	Editing of existing messages is not supported in this version.
