* Added Odom Sensor option
* Odom Sensor: Added pose time offset parameter
* Gui: fixed odom cloud not shown when rgb/depth doesn't have same size. Odom sensor: fixed rawImages set on non-stereo camera (because stereoRectify wrongly set to all cameras)
* Calibration: fixed rgb and depth suffixes not correctly set. OpenNI2: horizontal and vertical shifts can be also set for default calib.
* Fixed a warning
* OdomSensor: added option to use odom sensor output as ground truth (for comparison between odom sensor and rtabmap odom). Added scale factor option.
* FindG2O.cmake: updated path suffixes to find EXTERNAL csparse
* Pose3GravityFactor: fixed dllimport error on windows
* UI: Statistics panel not updated if not visible and keep stats in cache is unchecked. Added description to some timing debug logs in processStatistics().
* Removed vtkOutputWindow on Windows
* Odom Sensor: added zed sdk support
* bump version 0.20.11
Memory management tested on RGBD SLAM
Fixed some crashes
New parameter RGBD/LocalLoopDetectionMaxDiffID
New parameter LccIcp2/VoxelSize
Updated parameter LccIcp/Type (added "No ICP" type)
Updated parameter kLccBowMinInliers (inliers minimum reduced to 1)
TORO optimization: The graph root is explicitly defined as the last node added (fixed a TORO crash when a root could not be found)
TORO optimization: only one constraint between neighbors and loop closures
TORO optimization: added initial tree guess
Map correction/Map transform: now only used in localization mode (map correction is always identity on mapping mode)
New statistics: local loop space diff, last loop closure parent and child ids
Database: Fixed empty signatures with no poses loaded
ICP: fixed transform multiplication order
Dump memory: added 3D words
DatabaseViewer: added Export option (added ExportDialog object)
DataRecorder: Option recording in RAM or Hard drive
GUI: added a dock widget (MapVisibilityWidget) to change visibility of nodes in the 3D map
GUI: fixed progress bar step count when generating the map
Menu option: generate TORO graph (full/current map, optimized/not optimized)
Menu option: download map (full/current map, optimized/not optimized)
Preferences: added Reset all settings button
Preferences: A QGroupBox can be a boolean parameter
