Tune model

[anavarro01]

Hi, i am trying to tune my Gurobi model, calling de tune function (https://www.gurobi.com/documentation/9.1/refman/py_model_tune.html). I followed the instructions from #138 , but it seems to not work at the 9.1 version. There is any waiy to use this utility?

Use the C API:

Gurobi.jl/src/gen91/libgrb_api.jl

Lines 833 to 835 in 6484ba9

	function GRBtunemodel(model)
	ccall((:GRBtunemodel, libgurobi), Cint, (Ptr{GRBmodel},), model)
	end

using JuMP, Gurobi
jump_model = direct_model(Gurobi.Optimizer())
model = backend(jump_model)
GRBtunemodel(model)

You should consult the Gurobi documentation for more details.

Closing because this isn't an issue in Gurobi.jl.

Issue #412 is tracking the addition of documentation for accessing the C API.
