/**
\class THcTrigApp
\ingroup Apparatuses

\brief A mock spectrometer to hold all trigger related data.

This class behaves as a spectrometer apparatus, but it does not correspond to
any physical spectrometer in the hall. Its purpose is to gather all the trigger
related data.

Use only with THcTrigDet class.

/**
\fn THcTrigApp::THcTrigApp(const char* name, const char* description)

\brief A constructor.

\param[in] name Name of the apparatus. Is typically "T".
\param[in] description Description of the apparatus.

\fn virtual THcTrigApp::~THcTrigApp()

\brief A destructor.

/**
\fn Int_t THcTrigApp::Reconstruct()

\brief Does nothing and returns 0.

This function is usually responsible for reconstructing the event from the
detectors in the spectrometer. Since this is a mock apparatus, we have a mock
reconstruction.

\fn std::string THcTrigApp::GetKwPrefix()

\brief Returns prefix used for parameters in `param` files.

All the parameters read by this apparatus are prefixed with the returned string.
