Simpler keyframe insertion policy regarding stereo points.\n Added EuRoC mono and stereo examples. \n Some bug fixes.
Make clearer that SaveTrajectoryKITTI and SaveTrajectoryTUM do not work for monocular.
SaveTrajectory functions retrieve full frame trajectory using relative rigid body transformations between each frame and its reference keyframe. This relative transform is computed when the frame was tracked. This is inaccurate in the monocular case, as each relative transformation is computed at the particular scale when each frame was tracked. A global scale change will make all relative transformations invalid, and this can happen in two cases:
1) At loop closure
2) When the map is small and all keyframes are optimized in the Local BA. In that case the scale is not fixed and can change.
