Adds a row to the model.
Assembly: Microsoft.Solver.Foundation (in Microsoft.Solver.Foundation.dll)
If the model already includes a row referenced by the specified key, this sets the vid to the row index and returns false. If the model already includes a user variable referenced by the specified key, it sets the vid to -1 and returns false. Otherwise, it adds a new row associated with key to the model, assigns the next available index to the new row, sets vid to this index, and returns true. The CompactQuasiNewtonSolver can only have one row. By convention this row will always have 0 as an index.
