Detailed Description
The Matrix class.
For purposes of multiplication, points should be thought of as row vectors
to be right-multiplied by transformation matrices of the form
![\[ \left[ \begin{array}{ccc} c_0&c_1&0 \\ c_2&c_3&0 \\ c_4&c_5&1 \end{array} \right] \]](form_1.png)
(so the columns of the matrix correspond to the columns (elements) of the result, and the rows of the matrix correspond to columns (elements) of the "input").
