* Refactored RegistrationIcp so that libpointmatcher yaml can work with icp odometry (we can then avoid refiltering data with local map of F2M). All data filtering (including libpointmatcher DataFilters) are done at the beginning of the function.
* ICP: Restored ref and data scans order for libpointmatcher (seems more stable this way).
* Fixed compilation error without libpointmatcher
* CCCoreLib integration (Icp/Strategy=2). Icp/PMForce4DoF is now Icp/Force4DoF. Icp/PM is now Icp/Strategy. Icp/PMOutlierRatio is now Icp/OutlierRatio.
* Fixed build without CCCoreLib
* Cleanup RegistrationIcp from third party functions.
* Preferences: disable libpointmatcher and cccorlib options if not available

-Modified "Kp/DetectorStrategy=6", "Kp/MaxFeatures=500", "Mem/UseOdomFeatures=true", "GFTT/QualityLevel=0.001", "GFTT/MinDistance=3", "RGBD/OptimizeMaxError=1", "RGBD/ProximityPathFilteringRadius=1", "Odom/GuessMotion=true", "Odom/VisKeyFrameThr=150", "OdomF2M/BundleAdjustment=1", "Vis/Iterations=300" if built with g2o, "OdomF2M/BundleAdjustmentMaxFrames=10", "OdomFovis/MinFeaturesForEstimate=20", "OdomORBSLAM2/MapSize=3000", "Reg/RepeatOnce=true", "Vis/PnPRefineIterations=0" if built with g2o, "Vis/CorGuessMatchToProjection=true", "Vis/BundleAdjustment=1" if built with g2o, "Icp/MaxCorrespondenceDistance=0.1", "Icp/PointToPlaneK=5", "Icp/PointToPlaneRadius=1", "Icp/PM=true" if built with libpointmatcher, "Stereo/MaxLevel=5", "Stereo/MinDisparity=0.5".
BayesFilter: optimized prediction matrix update. Use of new argument "ignoreLocalSpaceLoopIds" of Memory::getNeighborsId() to ignore loop closure link by space in prediction update.
CameraThread: Added stereo exposure compensation option.
CameraRGB: Added forceGroundNormalsUp option and added support of ground truth from EuRoC dataset.
Statistics: Added "Memory/RAM_usage/MB".
Transform: Added clone() method to do deep copy.
Graph::importPoses(): EuRoC format support (9).
Rtabmap: Local visual loop closures are now identified as GlobalClosure link type.
OccupancyGrid/OctoMap: updated how cache is used (old node retrieved can be re-added to map without re-assembling the whole map).
OdometryF2F: when using ICP, increasing correspondence distance for first two frames. If Vis/CorType=1 and registration fails, second guess without motion is done with Vis/CorType=0.
OdometryF2M/RegVis: updated how features are removed from the map, using new projectedIDs filled in RegistrationInfo by RegistrationVis.
OdometryORBSLAM2: Maximum size of the feature map can be set with "OdomORBSLAM2/MapSize" parameter.
CloudViewer: fixed opengl camera drifting in follow mode.
DatabaseViewer: Added optimization scale option. ConstraintsView: hide loop closure links if type is ignored in gui parameters.
MainWindow: Support of "GridGlobal/MaxNodes" parameters when updating the maps.
UPlot: don't show ellipses when not in graphics view mode, updated how "random" colors are attributed to curves
Added rtabmap-euroc_dataset tool. Updated rtabmap-kitti_dataset and rtabmap-rgbd_dataset tools.
Added rtabmap-reprocess tool.
-CreateSimpleCalibrationDialog updated to create mono/stereo calibration files with advanced option (setting intrinsics of each camera + extrinsics between them). Rectification R and new camera P matrices are then automatically computed.
-Added GeodeticCoords class for convience conversion between GPS values (latitude/longitude/altitude) to local coordinate (ENU).
-Added support of Malaga Urban and St Lucia ground truths.
-CameraImages: added option to debayer images. Timestamps file: added support of "sec millisec" format.
-Added UException class: exceptions are sent instead of exiting the application on UASSERT or UFATAL.
Added Feature2D::generateKeypoints3D() for convenience.
Added parameter "Vis/PnPOpenCV2".
Added parameter "Vis/ForwardEstOnly".
Removed OdometryOpticalFlow class, replaced by OdometryF2F (frame-to-frame). To get the same previous OpticalFLow approach, parameter "Vis/CorType" should be set to 1.
Some parameters under group "OdomFlow/..." are now under "Vis/CorFlow...".
In Registration class, add computeTransformationMod() method to modify input signatures.
Added constructor Signature(SensorData) for convenience.
Modified words multimap used with cv::Point3f instead of pcl::PointXYZ to limit the use of PCL headers where they are not really required.
Added Stereo::create() for convenience.
Transform: fixed quaternion constructor where data_ was not initialized. Added parentheses operator for convenience.
DatabaseViewer: loading .rtabmap/rtabmap.ini instead of .rtabmap/dbViewer.ini when used from rtabmap application. Added vertical layout option for convenience.
MainWindow: fixed wrong Odometry speed values
ParametersToolBox: using QStackedWidget instead of a QToolBox for space, added "Restore Defaults" button.
-Added parameter "Mem/ReduceGraph" with new link type (NeighborMerged)
-DatabaseViewer: add Info panel, fixed empty extracted database when "RGB images" is not checked
-ConsoleWidget: added buffer size and refresh rate options
-DBDriver: new database info getters
-Graph: added reduceGraph() method, added Dijsktra computePath() with links only
-Updated default parameters: RGBD/LocalLoopDetectionSpace=true, RGBD/LinearUpdate=0.1 and RGBD/AngularUpdate=0.1
-Goals are saved with label instead of ID if the target node has a label
-DataRecorder: fixed saving incrementally the database (instead of only at the end)
-MainWindow: When waypoints are used, resend the current goal (1 sec delay) if it has failed setting it
