+  The constructor function retrieves pointers to the UEFI HII protocol instances
+
+  The constructor function retrieves pointers to the four UEFI HII protocols from the
+  handle database.  These include the UEFI HII Font Protocol, the UEFI HII String
+  Protocol, the UEFI HII Image Protocol, the UEFI HII Database Protocol, and the
+  UEFI HII Config Routing Protocol.  This function always return EFI_SUCCESS.
+  All of these protocols are optional if the platform does not support configuration
+  and the UEFI HII Image Protocol and the UEFI HII Font Protocol are optional if
+  the platform does not support a graphical console.  As a result, the consumers
+  of this library much check the protocol pointers againt NULL before using them,
+  or use dependency expressions to guarantee that some of them are present before
+  assuming they are not NULL.
+
+  @param  ImageHandle   The firmware allocated handle for the EFI image.
+  @param  SystemTable   A pointer to the EFI System Table.
+
+  @retval EFI_SUCCESS   The constructor always returns EFI_SUCCESS.
