Description

Implements test of 1-4 interactions.

This test is copied from the bonded interactions test and slightly modified since 'do_pairs' takes a different set of arguments than 'calculateSimpleBond'. To keep the test setup uncluttered this test is therefore not merged into the bonded test but implemented standalone.

The test setup consists of 2 atom pairs that are tested in an fep setting (vanishing charge and lennard-jones parameters of one atom) and without fep. Placement of the atoms in the box is such that shift-forces and pbc paths in do_pairs are covered.
