	AD
	Contains routines for the reverse mode of AD. In case there is no reverse type configured, they have no effect at all.

Functions
void	AD::StartRecording ()
	Start the recording of the operations and involved variables. If called, the computational graph of all operations occuring after the call will be stored, starting with the variables registered with RegisterInput.

void	AD::StopRecording ()
	Stops the recording of the operations and variables.

void	AD::RegisterInput (su2double &data)
	Registers the variable as an input. I.e. as a leaf of the computational graph. More...

void	AD::RegisterOutput (su2double &data)
	Registers the variable as an output. I.e. as the root of the computational graph. More...

void	AD::ClearAdjoints ()
	Clears the currently stored adjoints but keeps the computational graph.

void	AD::ComputeAdjoint ()
	Computes the adjoints, i.e. the derivatives of the output with respect to the input variables.

void	AD::Reset ()
	Reset the tape structure to be ready for a new recording.

void	AD::ResetInput (su2double &data)
	Reset the variable (set index to zero). More...

void	AD::SetPreaccIn (const su2double &data)
	Sets the scalar input of a preaccumulation section. More...

void	AD::SetPreaccIn (const su2double *data, const int size)
	Sets the input variables of a preaccumulation section using a 1D array. More...

void	AD::SetPreaccIn (const su2double const data, const int size_x, const int size_y)
	Sets the input variables of a preaccumulation section using a 2D array. More...

void	AD::StartPreacc ()
	Starts a new preaccumulation section and sets the input variables. More...

void	AD::SetPreaccOut (su2double &data)
	Sets the scalar output of a preaccumulation section. More...

void	AD::SetPreaccOut (su2double *data, const int size)
	Sets the output variables of a preaccumulation section using a 1D array. More...

void	AD::SetPreaccOut (su2double **data, const int size_x, const int size_y)
	Sets the input variables of a preaccumulation section using a 2D array. More...

void	AD::EndPreacc ()
	Ends a preaccumulation section and computes the local Jacobi matrix of a code section using the variables set with SetLocalInput(), SetLocalOutput() and pushes a statement for each output variable to the AD tape.
