Detailed Description

A dataclass that holds the data needed to create the path for a trajectory.

turning_radius: The radius of the circle used to generate
    the arc of the path
x_offset: The x coordinate of the circle used to generate
    the arc of the path
y_offset: They y coordinate of the circle used to generate
    the arc of the path
end_point: The end coordinate of the path
start_angle: The starting angle of the path
    - given in radians from -pi to pi where 0 radians is along
        the positive x axis
end_angle: The end angle of the path
    - given in radians from -pi to pi where 0 radians is along
        the positive x axis
left_turn: Whether the arc in the path turns to the left
arc_start_point: Coordinates of the starting position of the arc
arc_end_point: Coordinates of the ending position of the arc
