Functions
template<typename T >
T	plb::fd::ctl_diff (T u_p1, T u_m1)
	Second-order central gradient (u_p1 = u(x+1)).
template<typename T >
T	plb::fd::fwd_diff (T u_0, T u_1, T u_2)
	Second-order forward gradient (u_1 = u(x+1)).
template<typename T >
T	plb::fd::bwd_diff (T u_0, T u_1, T u_2)
	Second-order backward gradient (u_1 = u(x-1)).
template<typename T >
T	plb::fd::o1_fwd_diff (T u_0, T u_1)
	First-order forward gradient (u_1 = u(x+1)).
template<typename T >
T	plb::fd::boundaryZeroGradient (T u_1, T u_2)
	Value at u_0 for which asymmetric gradient is zero (u_1 = u(x+1)).
template<typename T >
T	plb::fd::linearInterpolate (T u_0, T u_1, T pos)
	Linear interpolation (yields u0 at pos=0 and u1 at pos=1).
