Added Bundle Adjustment options to OdometryF2M (OdomF2M/BundleAdjustment) and RegistrationVis (Vis/BundleAdjustment). Added logger thread filter. RegistrationVis: Copy back corresponding input word IDs to output words when available. Memory::computeTransform() added option to use already computed corespondences if possible (proximity detection by time uses this). Updated Optimizer::optimizeBA() interface.
