Public Member Functions
	FormCoefficients (const std::vector< std::tuple< int, std::string, std::shared_ptr< function::Function >>> &coefficients)
	Initialise the FormCoefficients, using tuples of (original_coeff_position, name, shared_ptr<function::Function>). The shared_ptr<Function> may be a nullptr and assigned later.

int	size () const
	Get number of coefficients.

std::vector< int >	offsets () const
	Offset for each coefficient expansion array on a cell. Used to pack data for multiple coefficients in a flat array. The last entry is the size required to store all coefficients.

void	set (int i, std::shared_ptr< const function::Function > coefficient)
	Set coefficient with index i to be a Function.

void	set (std::string name, std::shared_ptr< const function::Function > coefficient)
	Set coefficient with name to be a Function.

std::shared_ptr< const function::Function >	get (int i) const
	Get the Function coefficient i.

int	original_position (int i) const
	Original position of coefficient in UFL form.

int	get_index (std::string name) const
	Get index from name of coefficient. More...

std::string	get_name (int index) const
	Get name from index of coefficient. More...
