In \(\triangle ABC\) above, \(\angle A={66}^\circ,\) \(M\) is the midpoint of side \(\overline{BC},\) and \(D\) and \(E\) are the feet of perpendicular drawn from \(M\) to \(\overline{AB}\) and \(\overline{AC},\) respectively. If \(\lvert{\overline{MD}}\rvert=\lvert{\overline{ME}}\rvert,\) what is the measure of \(\angle CME ?\)
