HI: Analytic Frequencies, scalar ZORA

Sample directory: adf/HI_SecDer_ZORA/

The main difference of this example to the previous examples is that a ZORA Hessian is calculated in this example, through the line:

RELATIVISTIC scalar ZORA

Furthermore, the suggestion to use high integration accuracy in the atomic spheres only is shown explicitly here.
