\brief The Teuchos Floating Point Operations Class.
The Teuchos_Flops class provides basic support and consistent interfaces
for counting and reporting floating point operations performed in
the Teuchos computational classes. All classes based on the Teuchos::CompObject
can count flops by the user creating an Teuchos::Flops object and calling the SetFlopCounter()
method for an Teuchos_CompObject.
