toQuaternion Method

Create this matrix to a quaternion. Note: This calculation requires this matrix to have unit length rows and columns. WARNING: There is frequent confusion over whether a "from quaternion" matrix is organized by rows or columns. If you find that the matrix seems to rotate by the opposite angle, transpose it.
