Scalar variable

[jbcaillau]

@PierreMartinon @gergaud The following definition (check local_test_exponential.jl) generates an error (problem Real vs. Vector):

ocp3 = Model(variable=true)
state!(ocp3, 2)
control!(ocp3, 1)
variable!(ocp3, 1)
time!(ocp3, 0, Index(1))
constraint!(ocp3, :initial, [0,0], :initial_constraint)
constraint!(ocp3, :final, [1,0], :final_constraint)
constraint!(ocp3, :control, -1, 1, :control_constraint)
constraint!(ocp3, :variable, 0.1, 10, :variable_constraint)
dynamics!(ocp3, (x, u, v) ->  [x[2], u])
objective!(ocp3, :mayer, (x0, xf, v) -> v)

Writing

objective!(ocp3, :mayer, (x0, xf, v) -> v[1])

instead is OK.

Ok, we will add this case !
