示例1: WhenLineSweepsPoint
/// <summary>
/// Enumerates the times and places, if any, where a moving line crosses a point during a time step.
/// The line's endpoints move at a constant rate along their linear paths.
/// </summary>
/// <remarks>Original code found here https://github.com/Strilanc/Methods/blob/master/Methods/Methods/LineSweepPoint/GeometryUtil.cs </remarks>
