public class Point
extends java.lang.Object
implements java.io.Serializable
```
A class representing a point in an N-dimensional Euclidean space. The underlying representation is a double-array. Changes to the elements of this double-array will also result in a change to the point. The double-array can be specified on construction and can be retrieved lated.
