Package curve.area

Class Layer

java.lang.Object

curve.area.Layer

public class Layer
extends Object

See curve.area.Board for comments on the dot backing array.
Layer holds the descriptive collections of points and lines.
x+ is up, so x is mirrored from the dots array
dots 0, 0 maps to top left cornerof user screen
The user screen shadows the layers with a scaling factor
so x = horPixels/2, y = 0 will start to show in the middle lhs
The y axis is shared by both
May need an index from id to line
