Sets bounds for column J in the given problem. Argument BOUNDS specifies the type and bounds for the specified column. It can take one of the following forms:

'(unbounded)Free (unbounded) variable, -Inf <= x <= +Inf
'(lower-bound LB)Variable with lower bound, LB <= x <= +Inf
'(upper-bound UB)Variable with upper bound, -Inf <= x <= UB
'(double-bounded LB UB)Double-bounded variable, LB <= x <= UB
'(fixed LB UB)Fixed variable, LB = x = UB
