Log message:
	Added public enums Control_Parameter_Name and Control_Parameter_Value:
	for the time being, the only control parameter name is PRICING for
	the pricing method, which can be set to three values.
	Added public methods for getting/setting a control parameter value.
	Modified the implementation so as to compute the simplex by using the
	pricing method specified by the control parameter settings.
	
	As for implementation, we temporarily use a Control_Parameter_Value variable
	(named `pricing') to store the singleton control parameter collection.
	It is planned that this will be replaced by a bitset-based status
	word encoding, besides possible other control parameters, also the
	values of `status', `initialized' and `opt_mode'.
