! Overview:
!
! PBSA models the electrostatic solvation interaction by the Poisson-Boltzmann
! equation. The implementation (module poisson_boltzmann) uses the finite-
! difference method to solve the partial differential equation. Both linear
! and full nonlinear numerical solvers are implemented. Please refer to the
! following publications:
!
! 1. Luo, David, and Gilson, J. Comp. Chem. 23:1244-1253, 2002.
! 2. Qin, Wang, Zhao, and Luo, J. Chem. Phys. 130:14501, 2009.
! 3. Wang and Luo, J. Comp. Chem. In Press, 2010.
!
! for implementation details of the linear solvers. The full nonlinear solvers
! are documented in:
!
! 1. Cai, Wang, and Luo, J. Chem. Comp. Theo. In Press, 2009.
!
! The electrostatic energy and forces are computed based on the finite-
! difference grid potentials as discussed in the following publications:
!
! 1. Lu and Luo, J. Chem. Phys. 119:11035-11047, 2003.
! 2. Xiang, Wang, and Luo, J. Chem. Phys. Submited. 2009.
!
! The dielectric models and molecular surface used in the electrostatic 
! solvation model are documented in:
!
! 1. Wang, Ye, and Luo, J. Phys. Chem. Submitted, 2009.
! 2. Ye and Luo, J. Phys. Chem. Submitted, 2009.
!
! The parameters used in the electrostatic solvation model are documented in
! the following publication:
!
! 1. Tan, Yang and Luo, J. Phys. Chem. 110:18680-18687, 2006.
!
! PBSA models the nonelectrostatic solvation interaction by two separate
! terms, dispersion (or van der Waals or attractive) and cavity (or
! hydrophobic or repulsive), in this implementation (module dispersion_cavity).
! The dispersion term is computed by a numerical integration over the solvent
! accessible surface area. The cavity term is modeled by a term proportional to
! the molecular surface or volume with a single proportional constant. See the
! following publication for details:
