New release R20160923

Ouch, over a year since last release. Definitely overdue.

uncertain is now overloaded on constraints for easy definition of uncertain variables and constraints at the same time.
bisection can now be used as a solver, i.e., called via optimize.
Early experimental support for multi-parametric solver POP.
sort now supports matrix argument.
max and min now support location output in their mixed-integer versions.
interp1 overloaded as a callback operator.
Rotated second-order cones can be detected from model.
Added momentmodel to create a moment relaxation model without solving it.
robustify is now called robustmodel.
compilesos is now called sosmodel.
Performance improvements in nonlinear manipulations contributed by Ingmar Gundlach.
Performance improvements in variable indexing contributed by J.D. Bancal.
Breaking: bisection now assumes minimization (to be consistent with all other commands).
