Non-templated empty base class for template managers.
Wrapper to PHX::EvaluatorWithBaseImpl that implements Panzer-specific helpers.
bool checkApplyBC_

virtual Teuchos::RCP< CloneableEvaluator > clone(const Teuchos::ParameterList &pl) const
Pushes residual values into the residual vector for a Newton-based solve.
