[Cgl] Re: Numerical precision in cut generators

[Robin Lougee-Heimer]

In July,  Francois proposed using standard variables for handling 
numerican precision, e.g., 
   EPS: Precision of double computations. Default value: 1e-7.

I agree - we should have a standard. It makes a lot of sense. 

The list of standards he proposed was based on CglRedSplit, and CglGomory. 
 It seemed a bit of overkill to me, but if  they were necessary/useful for 
Gomory and RedSplit then it seems a reasonable list to begin.

----> Does anyone else have any thoughts/comments? 

Silence will be taken as thunderous approval, and the next step would be 
asking each CG-maintainer to update their CG.
