MGStraight is a curve of any space dimension, represent a straight line.
Parameterization of the MGStraight is as below using parameter t: point(t) = m_root_point + t*m_direction. MGStraight can be a line segment that has start and end points. Let t be the parameter of the straight line(i.e. length from m_root_point), then straight lien f(t) can be expressed as: f(t)=m_root_point+m_direction*t.
