Advanced methods for imprecise probabilities

[andreaperin]

The computational effort required by the implemented DoubleLoop and RandomSlicing techniques for managing imprecise probabilities may render them impractical.
Advanced techniques such as NISS and/or CABO should be implemented

I will start this week to do something with NISS @AnderGray @FriesischScott
