Public Member Functions
	MinModLimiter (const double &m=0.0, const bool &muscl=false)

double	minmod (Vector< double > &args)
	The basic minmod function.

double	minmodB (Vector< double > &args, const double &h)
	The modified minmod function.

void	limit (const unsigned &i, const Vector< DGElement * > &required_element_pt)
	The limit function.

Public Member Functions inherited from oomph::SlopeLimiter
	SlopeLimiter ()
	Empty constructor.

virtual	~SlopeLimiter ()
	virtual destructor

Private Attributes
double	M
	Constant that is used in the modified min-mod function to provide better properties at extrema.
