Bug Fixes and Logger

-Fixed Bug with incorrect labeling in loader
-Fixed camera position
-Fixed boundries to keep within table markers
-Fixed collision avoidance code to act on mesh size and scale for more
accurate positioning
-Added retry counter for object placement to avoid infinite looping on
broken meshes
-Added logger scripts to components we're interested in and the global
logger to start logging each trial

TODO:
-Clean up the GUI a little on Loader scene
-Optimize logger to avoid printing redundant data (just print time stamp
and "clone" marker to show that the data did not change between frames)
-Added mouse click-and-drag along plane for objects
