AddSurrogateAction

This action adds SurrogateModel objects contained within the [Surrogates] block. For example, the following block adds a PolynomialChaos surrogate model.

[Surrogates<<<{"href": "../../syntax/Surrogates/index.html"}>>>]
  [poly_chaos]
    type = PolynomialChaos<<<{"description": "Computes and evaluates polynomial chaos surrogate model.", "href": "../surrogates/PolynomialChaos.html"}>>>
    trainer<<<{"description": "The SurrogateTrainer object. If this is specified the trainer data is automatically gathered and available in this SurrogateModel object."}>>> = poly_chaos
  []
[]
