2658015cda [poincare] Fix mis-implementation of (a^b)^c -> a^(b*c) which is applied 
if:
- a > 0
- in Real: when b and c are integers
- in other modes: when c is integer

3adbca88d8 [poincare] TreeHandle: Improve BuildWithBasicChildren 
When building ghost nodes to stand as temporary children, we do not need
to move them are they are built sequentially after the built node.

fad3ad958d [poincare] SymbolAbstract: the node alignment is handled by the TreePool 
and the TreeNode classes. SymbolAbstract and its children class don't
need to watch the alignment.
