Public Class methods

new(*args) 
 Point position, in model coordinates (a 3-element array)

 Returns an initialized InfoPoint instance.

4 args

 aPoint = InfoPoint.new(Csys, 3.0, 3.0, 0.0)
 a new point at position (3.0, 3.0, 0.0), @info = [@parent, self, "p#{@@count}"]
 where @parent = self

5 args

 aPoint = InfoPoint.new(Csys, 3.0, 3.0, 0.0, [info0, info1, info2])

6 args

 aPoint = InfoPoint.new(Csys, 3.0, 3.0, 0.0, @parent, @text)

 Should InfoPoint have the same initialization as Lines?
 def initialize(@parent, @ref, *args)
 only possible reference is csys?
