Plot 3D vectors/arrow (again ...)

The goal for me was to draw some reference frames to illustrate coordinate systems. I used arrow3 for a while, it was very usefull and I liked some of its features, but I had a few problems with it. 1/ 'deformation' problemns when applying functions like 'axis equal' when different objects are present, 2/ color problems when other colored objects were present and 3/ need for a 3D line-part of the arrow. So, the present function is much more limited than arrow3 in terms of functionalities, but attempts to solved the problems previously exposed. At least it worked for me, I hope it may be usefull for others...
