Grids and Axes for Coordinate systems
and Visualizations of Mathematical Functions

(uses javascript to show some sample images in 600x450 pixels)

	1.	Squared Paper (Objects: plane. Methods: color_map, layered textures, #macro.)
	2.	Systems of Coordinates with Axes (Objects: cone, cylinder, plane. Methods: declare, union, #macro.)
	2.	Grids with 2 Levels (Objects: cone, cylinder, plane. Methods: #macro #declare, union.)
	3.	Visualization of Mathematical Functions in a 2D System of Coordinates (Objects: cone, cylinder, sphere. Methods: #declare, union, #macro, #while.)
