Public Member Functions
	PebbldBranchSub ()
	Constructor.
	~PebbldBranchSub () override
	Destructor.
PebbldBranching *	global () const
	Returns a reference to the corresponding main Branching object.
pebbl::branching *	bGlobal () const override
	Returns a reference to the corresponding main Branching object.
void	setGlobalInfo (PebbldBranching *global_)
	Method that sets up the main Branching object.
void	setRootComputation () override
	Method that is called when declaring the current node as a root node.
void	boundComputation (double *controlParam) override
	Method that does the Bounding Operation. In other words, it calls the optimization algorithm on the relaxed domain.
bool	candidateSolution () override
	Method called after the bounding operation, returns true if the bounding resulted in a possible solution to the original non-relaxed problem.
pebbl::solution *	extractSolution () override
	Method that returns a PEBBL-based solution.
int	splitComputation () override
	Method that determines how many branches are created and how. Returns the number of branches created from this object.
pebbl::branchSub *	makeChild (int whichChild) override
	Method that returns a new PebbldBranchSub object based on Objective Function improvements and the number of branches.
void	pebbldSubAsChildOf (PebbldBranchSub *parent, int splitVar, int whichChild, std::vector< double > _candidate_x, RealVector _lower_bounds, RealVector _upper_bounds)
	Method that creates a new PebbldBranching object.

Protected Attributes
PebbldBranching *	globalPtr
	Pointer referring to all info passed to subproblem.
std::shared_ptr< Model >	subModel
	Model used for sub-problem.
std::shared_ptr< Iterator >	subNLPSolver
	Solver used for sub-problems.
std::vector< double >	candidate_x
	Candidate solution after solving sub-problem (also the bound)
double	candidate_objFn
	Objective value at the candidate solution.
int	splitVar
	Variable to branch on.
RealVector	cont_vars
	Initial variable values for sub-problem.
RealVector	lower_bounds
	Lower bounds for sub-problem.
RealVector	upper_bounds
	Upper bounds for sub-problem.
