Parameters:
{JXG.Point|Array_JXG.Point|Array_JXG.Point|Array_JXG.Point|Array_JXG.Point|Array} a,b,c,d,e
Parent elements are five points.


{Number_Number_Number_Number_Number_Number} a_00,a_11,a_22,a_01,a_12,a_22
6 numbers


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create a conic section through the points A, B, C, D, and E.
 var A = board.create('point', [1,5]);
 var B = board.create('point', [1,2]);
 var C = board.create('point', [2,0]);
 var D = board.create('point', [0,0]);
 var E = board.create('point', [-1,5]);
 var conic = board.create('conic',[A,B,C,D,E]);
