Computes the baryon density field from the log-enthalpy field and extra parameters.

Parameters

ent	[input, unit: ] log-enthalpy H defined by $H = c^2 \ln\left( {e+p \over m_B c^2 n} \right)$ , where e is the (total) energy density, p the pressure, n the baryon density, and the baryon mass
nzet	number of domains where the baryon density is to be computed.
l_min	index of the innermost domain is which the baryon density is to be computed [default value: 0]; the baryon density is computed only in domains whose indices are in [l_min,l_min+nzet-1] . In the other domains, it is set to zero.
par	possible extra parameters of the EOS

Returns: baryon density [unit: $n_{\rm nuc} := 0.1 \ {\rm fm}^{-3}$ ]
