Create a new ConicSection. <br/>
A, B, C, D, E, and F are the same as in the equation.

`::discrimiant` <br/>
A property, which calulates the discrimiant. <br/>
It uses `B^2 - 4AC`

`::type` <br/>
Get the type of Conic Section. <br/>
It uses the table listed above, and return the class for that type of conic section.
