Solitude, a singular algebraic surface of degree four. This is the set of real points for which ```x^2*y*z +x*y^2+y^3+y^3*z-x^2*z^2 = 0.```

Has two holes, and two singular lines, one of which exists nakedly in the voids in the surface!

Provided are three files:
* `solitude_thickened.stl` -- has the normal vectors fixed, and is thickened for printing.
* `solitude_raw.stl` -- raw triangulation coming from Bertini_real. Since the program works in arbitrary dimensions, I make no effort t
