Library Constructor needed for Full Graphic Smart Controller

Amazon sells a terrific 3D printer kit that includes a bigtree-tech.com Full Graphic Smart Controller and everything needed to hook it up to a mega 2560 and RAMPS board. The whole kit is $34 and includes the mega 2560 and ramps board and all connectors.

The u8glib libraryfor displays such as this requires a suitable Constructor for the specific display being used.

Can someone tell me what the constructor for this particular display is?
