Following features are contained in the initial release of the IntegralEvaluator:
- Born--Oppenheimer (BO) and pre-BO one- and two-body integrals.
- Storing of one-body integrals in memory.
- Storing of two-body integrals in memory.
- Direct Fock matrix evaluation routines for BO and pre-BO.
- Cauchy--Schwartz screening for the BO contribution to the Fock matrix.
- First derivatives of one- and two-body integrals.
