Parent elements are a point and a line or a pair of coordinates. Optional parameters three and four are numbers which define the curve length (e.g. start/end). Default values are -π and π.

Examples
Create a parabola by a point C and a line l
var A = board.create('point', [-1,4]);
var B = board.create('point', [-1,-4]);
var l = board.create('line', [A,B]);
var C = board.create('point', [1,1]);
var el = board.create('parabola',[C,l]);
Create a parabola by a point and a line, both given by coordinate pairs
var par = board.create('parabola',[[3.25, 0], [[0.25, 1],[0.25, 0]]]);
