* ImageView: Depth colormap in base frame option. CloudViewer: added min/max range options for XYZ axes coloring.
* CloudViewer: saving rendering options of the 3D view, re-apply current color index when moving through nodes.
* reset color inverted when reset
Refactored how features are stored in Signature (significative memory optimization, causing major refactoring in Memory, RegistrationVis, OdometryF2M)
FLANN: optimized memory usage when Kp/IncrementalFlann is false
Added memory usage functions
Added statistics Loop/Visual_inliers_ratio/ and Memory/RAM_estimated/MB
EpipolarGeometry: templated findPairs functions
graph::filterLinks: added inverted option
LocalBundleOnLoopClosure: Force to use only neighbor links
MainWindow: fixed max depth filtering for map's features
Rtabmap::getSignatureCopy() fixed links not returned
Added UPlot::getAllCurveDataAsText() function.
DbViewer: fixed features not rendered in right view when failing ro refine a constraint
report: added --export and --export_prefix options (to export figures data)
Added graph::importPoses().
Can now have a ground truth published with SensorData (filled optionally by CameraImages classes).
Increased database closing time performance when the database is not saved.
Added ParametersToolBox widget in DatabaseViewer for core parameters (refactoring done to make easy access to all rtabmap parameters in DatabaseViewer).
Added Parameters::getType(key).
Added Transform::interpolate() to interpolate between two transforms (SLERP)
Updated pf_filter.m and added test_pf_filter.m MATLAB scripts (making easier to compare with a ground truth)
UPlot: can now save all curve data of a figure in one action (see right-click on legend area->"Copy all curve data to clipboard")
