-'''what does the grow loop do?
-loop over all the roots (what are they? IvyNode instances?)
-
- check if root is alive else goto next root
- check if the ivy should die (against maxLength) set root.alive
-
- get thre Vecors toaiff determine the direction of growing
- primaryVector,
- randomVector (with a slight upVector addition),
- adhesionVector
-
- compute the growvector
- growVec = localIvySize * (primaryVector * primaryWeight *
- randomVector * randomWeight *
- adhesionVector * adhesionWeight)
-
- compute gravityVector
- gravVec = localIvySize * gravityVector((0,0,-1)) * gravityWeight
-
- change influence of gravity depending on floating length
- gravVec *= pow(root.floatinglength / local_maxFloatlength, 0,7)

-
- getattr position of the next IvyNode:
- nextPosition = root.position + growVec - gravVec
-
- test if ivy dies assert per collisiondetection
- set alive state
-
- update the growVecor for the newdir position (of whatsound exactly?)
- growVec = new_pos - root.pos - gravVec
-
-
-
- Create the next ivyNode
- tmpNode = ivyRoot()
-
- set the new Values for the tmpNode
- tmpNode.position = new_pos
-
- tmpNode.primaryDir = normalizedVector (
