Detailed Description

A helper class for drawing concentric circles to mark distance measurements on the LRF tester's main window.

This file defines a helper class for drawing concentric circles centered at the position of the laser range finder within the LRF test program's window. These circles mark distances at regular intervals.

For example, we can have markings every 100, 500, 1000 and 5000 mm. Each of these markings can be drawn in a different color. Thus, the 100 mm markings can be one color, the 500 mm markings another color, the 1000 mm markings yet another color, and, finally the 5000 mm markings in a fourth color. Furthermore, we can also specify the zoom ranges at which the 100, 500, 1000 and 5000 mm markings should be visible.

This helps make the laser range finder's distance measurements more readable and easier to interpret. It is usually much easier to read distances off such a "contour" map rather than trying to figure them out on a square grid.
