ns_SetLibrary

 ns_SetDLL   Opens a Neuroshare Shared Library (.DLL or .so) in prepearation for other work

    Usage:
        [ns_RESULT] = ns_SetLibrary('filename.dll')

    Description:
        Opens the dynamic linked library specified by filename

    Parameters:
        filename    Pointer to a null-terminated string that specifies the
                    name of the file to open. 

    Return Values:
        ns_RESULT   This function returns ns_OK if the file is successfully
                    opened. Otherwise one of the following error codes is 
                    generated:

                        ns_TYPEERROR    Library unable to open file type
                        ns_LIBERROR     File access or read error 

    Remarks:
        Any already opened libraries, as well as any open files will be closed
        immediately.

        All files are opened for read-only, as no writing capabilities have
        been implemented.  If the command succeeds in opening the file, the
        application should call ns_CloseFile for each open file before 
        terminating.

        This function has to be called before any other Neuroshare function
        is called.
