12    C !DESCRIPTION:
13    C Contains statement function defining limiter function.
14    C
15    C A trivial limit for the limiter recovers the upwind scheme:
16    C \begin{equation*}
17    C Limiter(Cr)=0
18    C \end{equation*}
19    C Lax-Wendroff is recovered with:
20    C \begin{equation*}
21    C Limiter(Cr)=1
22    C \end{equation*}
23    C The current limiter of choice is the "Superbee" limiter:
24    C \begin{equation*}
25    C Limiter(Cr)=max(0,max(min(1,2*Cr),min(2,Cr)))
26    C \end{equation*}
27    C which is the default.
