GRBModel::chgCoeffs()
Change a list of coefficients in the model. Each desired change is
captured using a GRBVar object, a GRBConstr object,
and a desired coefficient for the specified variable in the specified
constraint. The entries in the input arrays each correspond to a
single desired coefficient change. If you make multiple changes to
the same coefficient, the last one will be applied.
Note that, due to our lazy update approach, the change won't actually take effect until you update the model (using GRBModel::update), optimize the model (using GRBModel::optimize), or write the model to disk (using GRBModel::write).

Arguments:
constrs: Constraints for coefficients to be changed.
vars: Variables for coefficients to be changed.
vals: Desired new values for coefficients.
len: Number of coefficients to change (length of vars, constrs, and vals arrays).
