Self-balancing vinMoov

Now that the IK engine is working like I want. I can add more functionality to it.

I first start with a self-balancing positionning. So every time the vinMoov is ask to move a body part, the ik engine will adjust the rest of his body so the vinMoov can keep is balance (in theory, that will remain to see if it could work with a real inMoov) 

Reviewing IntegratedMovement service

Some time ago, I had want to add legs to my test model (InMoov) in the IntegratedMovement (IM) service, but find out that something was lacking to work properly. By example, using the jMonkey simulator, when I make the right knee bent, it work fine and raise the foot. but if I also bent the left knee, it would raise the left foot and the robot will appear to be flying, wich is not even close of that will happen with the physical robot. So I need to find a way to make IM model act more in jMonkey to what a real robot will act. 

How to fix IntegratedMovement service?

I am a bit annoyed by the recent change that broke the Integrated Movement service. In the past I was always take great care to not break anything that may used shared code. My code was maybe clobbering or misplaced, but was not affecting anything else. Now part of the code I used have been modified or removed and IM service is not working anymore.

What I was doing:

SDR (Software Defined Radio)

Software defined radio (aka SDR), is a way of automating tuning into Audio/Digital radio receptions.

I am using a very simple (un-nervingly sensitive) USB dongle type RTL-SDR.COM

(cost inclusive antenna & mount was < £25).
