Detailed Description

Abstract interface for classes which compute the points of closest approach of 2 helices.
For a pair of states, the calculate methods have to be called before any of the other methods. This will do all calculations needed to get the result. It returns a status which says whether the calculation was successful. This should be checked before getting the result. If the status is false and the results querried, an exception will be thrown.
