Separated VidereCamera functionality in separate files, added disparity
image support... Have to organize all files and figure out why I can't
see disparity images properly (grayed out).

Removed old makefile since it's not useful anymore and separated the
basic VidereCamera interface for people to use outside ROS.
Changed path to calibration file to std::string
Added calibration file to Git

Amend: fixed accessors to calibration matrices
-Added launch files for standalone camera, stereo_image_proc pipeline
and calibration pipeline

-Renamed SVS calibration file so it is easily differentiated from OpenCV
calibration (still needs a parser+option)

-Removed the talker/listener nodes which are at this point useless

-Created ROS accessors for camera parameters

-Removed SVS rectification as default (maintaining error message for
now)

-Added misc changes in videre_camera_node to support ROS
stereo_image_proc pipeline
Added missing opencv calibration, edited stack+manifest.xml
Added license information
Added opencv2svs calibration file parser
Removed stereo_view from calibration.launch
Hard-coded OST and SVS calibration parameters... WORKED!

Important detail: mm -> m conversion needed in projection matrix coming
from SVS (specifically, P[3] needs to be multiplied by 0.001).
Added OST calibration for Athos, removed SVS calibration
MAJOR BUG FIX: ROS accessor for projection matrix was wrong!
Merge remote-tracking branch 'origin/master'
Added SVS+OST calibration file parsing (adapted from videre_stereo_cam
package)
Python script for OST to SVS calibration file conversion no longer
useful as of previous commit, removing it

Since the repository will be maintaining calibration files for multiple
cameras, I am also removing the old calibration files to start a new
naming convention for them: [computer name].[calibration file type]
Changed default image size to 640x480
Removed SVS disparity image display
Added check for failure to open calibration file
Added robocop calibration file

Explicitly added path to robocop calibration file

Corrected the frame where images were taken so rviz would not complain
Added Athos calibration file
Added launch files for data logging and general teleop with Pioneer robots
Added cmake_install.cmake to repository
Updated robocop.opencv calibration file
Removed image display from videre_camera_node.cpp
Added compression and prefix to rosbag in
camera+odometry+joystick+bag.launch
