描述----------Description----------
A subclass of virtual class “Stem” that can be used to represent standing trees. The class provides for creation and graphical display of “standingTree” objects.
虚拟类的子类“Stem”，可以用来表示的树木。这个类提供了用于创建和图形显示的“standingTree”对象。
Detail examples and information concerning this class is found in “The Stem Class” vignette, which should be consulted for more details on creating and using objects from this class.
在“干类”的小插曲，应咨询有关详细信息，创建和使用这个类的对象从详细的示例和信息，关于这个类被发现。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("standingTree", ...). However, this is not recommended. The object has a number of required slots that can be somewhat complex to calculate. Therefore, a constructor function standingTree has been provided that will make the desired object with the correct values for the slots. It is strongly recommended that one use this generic's methods to create
可以创建对象通过调用的形式new("standingTree", ...)。然而，这是不推荐的。的对象有许多需要的插槽，可以计算有点复杂。因此，一个构造函数standingTree已提供正确的价值观的插槽，这将使所需的对象。强烈建议使用这个通用的方法来创建
插槽----------Slots----------
Please note that all diameters below are presumed to be in the same units as height, i.e., meters for “metric”, and feet for “English” units.
请注意，所有直径小于被推定为是在高度相同的单位，即米的“公制”，和脚为“英语”units。
