 Return only the name of an (unopened) guide
------------------------------------------------------------------------------

 Function:      NGlook()

 Syntax:        NGlook(cFileName) --> cGuideTitle

 Description:   NGlook() will only return the name of a .NG file,
                this can be handy when one only wants to inpect the name
                of a .NG file, for display in a list or whatever..
                NGlook() is MUCH faster than NGopen(), NGname(), NGclose()
                in a row!

 Returns:       The name of the guide, or an Empty string ("") if the file
                is not a Norton Guide database.

 Example:       NGlook("EXPAND.NG")
                Might Return: "Clipper 5.01a . Expand Library v3.00"
