[ros-users] Bumblebee2 v1.0 release

[sh2723 at columbia.edu]

Hi Jack,

In the bumblebee2 package, the left and right image which are actually  
mono8 image is published even if I used the  
DC1394_VIDEO_MODE_640x480_MONO16 to grab the image from bumblebee.  
After grabbing 16bit image, I separate the one 16bit image into two  
8bit images and publish them.

Best,
Soonhac
