-Create a new variable in a formulation with given name and duties.

+Create a new variable that has name `name` and duty `duty` in the formulation `formulation`.
+
+Following keyword arguments allow the user to set additional information about the new variable :
+ - `cost`: cost of the variable in the objective function
+ - `lb`: lower bound of the variable
+ - `ub`: upper bound of the variable
+ - `kind`: kind which can be `Continuous`, `Binary` or `Integ`
+ - `is_active`: `true` if the variable is used in the formulation, `false` otherwise
+ - `is_explicit`: `true` if the variable takes part to the formulation, `false` otherwise (e.g. a variable used as a shortcut for calculation purposes)
+ - `members`: a dictionary `Dict{ConstrId, Float64}` that contains the coefficients of the new variable in the constraints of the formulation (default coefficient is 0).
