GLOBALINITCUTSTRATEGY

Description
Strategy for the initial tangent/secant convexification cuts added per nonlinear operator when setting up the initial LP relaxation during a global solve. Adding more cuts tightens the problem, resulting in a smaller branch-and-bound tree, at the cost of slowing down each LP solve.
