 * Description:
 * The PyRangeType is the type of ranges. The range type may be called, like
 * other types. Normally, when a type is called, like int(x) for instance, the
 * __int__ method is subsequently called on the object x. With range objects, 
 * when range(x) is called, a new range object is created to iterate from 0
 * to x-1. The range type may be called in one of several different ways with
 * arguments range(start, stop, increment). Both start and increment are 
 * optional and default to 0 and 1, respectively. 
 * 
 * Because of this different behavior when the range type is called, the
 * PyType implementation won't suffice to represent the range type. Instead,
 * this class is defined with its own special type behavior. That is, when 
 * the range type is called, a new range object is created and returned.
