Aim: A parallel strip in the space is the intersection of two parallel halfplanes such that each halfplane includes the other.
Description of template class 'ParallelStrip'
If N is the unit normal to one of the halfplane, the set of point X that is included in the strip satisfies some: \( \mu \le N \cdot X \le \mu + \nu \), where inequalities can be large or strict.
The normal to the strip is the vector N. The width of the strip is the scalar \(\nu\). The axis width of the strip is the quantity \(\nu / N_i\) where \(N_i\) is the greatest component.
Models: A ParallelStrip is a model of concepts::CPointPredicate.
TSpace  any digital space, i.e., a model of CSpace. 
muIncluded  when 'true', the first inequality is large, i.e. \( \mu \le N \cdot X \), otherwise it is strict, i.e. \( \mu < N \cdot X \) 
muPlusNuIncluded  when 'true', the second inequality is large, i.e. \( N \cdot X \le \mu + \nu\), otherwise it is strict, i.e. \( N \cdot X < \mu + \nu\)
