Detailed Description

Clearance information for one particular PTG and one set of obstacles.

Usage:

Declare an object of this type (it will be initialized to "empty"),
Call CParameterizedTrajectoryGenerator::initClearanceDiagram()
Repeatedly call CParameterizedTrajectoryGenerator::updateClearance() for each 2D obstacle point.
