Point file specification.

A point file is an extended xyz file. Coordinates are in Å. Extensions are attached as named sections after coordinate specification.

Section Description
ENERGY Energy in kcal/mol is provided on the next line.
GRADIENT Gradient is provided in kcal/mol/Å in three columns starting from the next line.
HESSIAN Hessian is provided in kcal/mol/Å^2 as the full square matrix.
WEIGHT weight of the point
CVS definition of collective variables for geometry restraining. The next line contains number of CVs. Description of each CV then follows.
ESP definition of electrostatic potential. The next line contains number of ESP points, followed by ESP points. Each ESP point has x, y, and z coordinate in Å and value of ESP (not yet determined).
