3    \brief Definition of a parenting node
4
5    parenting is how coordinates are handled in orxonox, meaning, that all coordinates
6    are representet relative to another parent node. this nodes build a parenting
7    tree of one-sided references (from up to down referenced).
8    Every node manages itself a list of childrens (of whos it is parent - easy...)
9
10    absCoordinate, absDirection have to be recalculated as soon as there was a change in
11    place or ortientation. this is only the case if
12    o bDirChanged is true (so changed) AND timeStamp != now
13    o bCoorChanged is true (so moved) AND timeStamp != now
14    this conditions make it cheaper to recalculate the tree (reduces redundant work).
15
16    remember: if you have to change the coordinates or the directions, use the functions
17    that are defined to execute this operation - otherwhise there will be big problems...
