Dispersion interface
This interface provides dispersion correction to DFT and some other methods. By default, the formulation and parameters of Jurecka et al[1] are used.
Atomic parameters are read from database file data/dispersion.yaml.
Parameters for the damping function differ for different methods or functionl/basis set combinations in DFT. If no parameters are provided by the dispersion_para keyword, cuby attempts to read default parameters for the method from the database file (it contains all parameters published in [1]), and raises an error if no parameters were found.
