Detailed Description

Class is STRATEGY pattern for mode construction. Includes method for selecting objects on page and manipulating with him.

This implementation is for selecting any operators on the page. If press left button and move mouse, and then release left button, mode select all oprators which are all inside the selected area. If press and then release left button (don't move), then mode select the last (top) operator which contains mouse button release position on the page. If press and then release left button over selected operator, mode select previous operator (operator which is first below now selected operators).
