Started a state-space model for the quad-rotor.
Started working on the infinite-horizon affine QR topology.
Finished the IHAQR topology, and the quadrotor model.
Started the MEAQR topology, fixed a few things in IHAQR topo, and on bounded-space concept and topos.
Finished the MEAQR and IHAQR, moving on to collision models.
Finished the X8 kinematics model (trivial).
Completed the geometric models of X8, starting to modify the RRT* algorithm to allow for dual metric.
Fixed some issues in the node-generators.
Created a MEAQR rrt* planner class, fixed the linear-search (pred / succ), and successfully compiled the linear-search MEAQR planner.
Fixed the issues for MEAQR RRT* planner. Completed implementation of unsymmetric metric spaces and DVP trees.
Finished the SBA* MEAQR planner, working on getting the ARE solver to work on the quadrotor system.
Did some testing with ARE solver, will add a controllable mode reduction to a "safe" LQR solver.
Created a function for controllability reduction, and integrated it to a special version of the IHCT-LQR solver. Starting to update the IHAQR for that.
Trying to fix the ctrl-decomp and reduced ARE solver. Some progress, but still some false positives.
Fixed most of the issues with the MEAQR-IHAQR topologies, seems reasonably stable now.
Added a post-T-optimal steering phase for the MEAQR steering function.
Added reduced sampler to IHAQR / MEAQR spaces. Created the planner testing program, and fixed some issues related to that (a bug in CD pairs, etc.).
Merge branch 'pp_dev' of github.com:mikael-s-persson/ReaK into pp_dev

The X8 RRT* planner works, fixed some issues with the frame-tracer.
Extended MEAQR metric and steering, removed the IHAQR (no longer a backup for MEAQR), much better results now.
