* Moved bin directory inside build directory (to make easier different builds with same source directory)
* Switched include order to avoid problems with remaining Version.h still in source directory taen before the one in binary dir. Fixed android build (updated res tool search path).
* workflow-cmake: fixed path to bin directory
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.
