Detailed Description
Input to ModelInstance.instantiate.
A Modifier consists either of a Parameter or a triple: A Variable or Equation to be modified, the modification action (e.g. Upper, Lower or Fixed for updating bounds of a variable, or Primal/Dual for updating the level/marginal of a variable or equation mainly used for starting non-linear models from different starting points), and a Parameter that holds the data for modification. In addition the UpdateType can be defined (if omitted the type defined in the Solve call is used).
