General mass/energy balance solver using GEKKO
Equality/inequality constraints. Keys prefixed eq/ge/le/gt/lt. Each entry: {'left': expr, 'right': expr}.
Decision variables. Each entry: [lb, init, ub] for free variable, or [fixed, fixed, fixed] for constant.
Objective to maximize. Format: {'left': 'maxtarget', 'right': 'expr'}.
Objective to minimize. Format: {'left': 'mintarget', 'right': 'expr'}.
