Speed up OEAMC
Problem: it takes ridiculously long to get OEAMC samples. What should be seconds takes minutes.
Examples:
- Simple running example is ready in the
AllTest>testFargstest (e.g. for100samples MCexp>OEAMC takes ca. 140 sec, ELexp>MEBS ca. 25 sec). - In TF toy example
testEssentialPars4awith 10 sample points it takes >30 sec.
Suspect: unnecessary ellipsoids estimations (resulting in many calls to lowner).
Remark: start w/ factoring out volestellip from OEAMC, and profile to see how much time is actually spent there.
