Setup RK steps for the ith stage:

Uf^i = ulast^i = CUf^{i0} Ui^i + CUf^{i1} ulast^i + CUf^{i2} dUexplicit^i + CUf^{i4} dUimplicit^i

unew^i = CUnew^{i0} Ui^i + CUnew^{i1} dUexplicit^i + CUnew^{i2} Uf^i + CUnew^{i4} dUimplicit^i

[SUPERNOTE: currently only TIMEORDER==4 has final unew different from final uf. This factis usd in utoprimgen.c to avoid inversion if requested, unless cannot because unew must itself be inverted.]

(how also used) CUf[timeorder][2] : t + dt*CUf[timeorder][3]+ dt*CUf[timeorder][2] = time of pf

CUf[timeorder][3] : t + dt*CUf[timeorder][3] = time of pi

CUnew[timeorder][3] : t + dt*CUnew[timeorder][3] = approximate time of pb

GODMARK: Currently RK methods all feed pf into pb on next step, so only need one pstag. In general should have multiple pstag's.
