Eve - singular algebraic surface

Eve, a singular algebraic surface of degree five. This is the set of real points for which
```
0.5*x^2 + 2*x*z^2 + 5*y^6 + 15*y^4 + 0.5*z^2 - (15*y^5 + 5*y^3) = 0.
```

Has two point singularities!

I have provided these files:
* `Eve_thickened_Blocky_R1_fixed.stl` -- has the normal vectors fixed, and is thickened for printing.
* `Eve_thickened_Smooth_R1.stl` -- the blocky version, ran through the `sampler` module for `bertini_real`.
* `eve_raw_blocky_r1.stl` -- raw triangulation c
