Slope limiter.

This subroutine limits the slope of the linear reconstruction of the physical variables, accordingly to the parameter "solve_limiter":

• 'none' => no limiter (constant value);
• 'minmod' => minmod slope;
• 'superbee' => superbee limiter (Roe, 1985);
• 'van_leer' => monotonized central-difference limiter (van Leer, 1977)

Parameters

[in]	v	3-point stencil value array
[in]	z	3-point stencil location array
[in]	limiter	integer defining the limiter choice
[out]	slope_lim	limited slope
