<p>Template plane class with some intersection testing methods. </p>
<p>It has to be ensured, that the normal is always normalized. The constructors and setters of this class will not ensure this automatically. So any normal passed in has to be normalized in advance. No change to the normal will be made by any of the class methods. </p>
