Create Arc2dfx and Arc2d

[sebpetit]

Create a constructor with the following parameters :

• le X coordinate of the center point of the arc
• the Y coordinate of the center point of the arc
• the lenght the angular extent of the arc in degrees (or the ending angle of the arc in degrees)
• the radius of the full ellipse of which this arc is a partial section
• the starting angle of the arc in degrees

The arcs will be based on an Elliptical shape. the constructors will be:

• Arc2d(double centerX, double centerY, double horizontalRadius, double verticalRadius, double startAngleInRadians, double endAngleInRadians)
• Arc2dfx(double centerX, double centerY, double horizontalRadius, double verticalRadius, double startAngleInRadians, double endAngleInRadians)

The arc will not be a piece of pie. In other words, It is on the perimeter of the base ellipse. It is not a polygon.

Do you need specific functions on arcs (excepting getting the closest/farthest point, distance, intersection)?
