56c45d1390 [poincare] Parsing: expression -> expression is always parsed but return 
"undef" when the left expression is neither a custom variable or
function nor a unit.
This makes the behaviour consistent on theses expressions:
2 -> a+a
2 -> 2*a

bf9653d510 [poincare/expression] Turn getUnit into extractUnits 
Addition::shallowReduce factors the unit across its terms.
Previously expressions of the form 1_m+π_m were reduced to undef.

7c79c70890 [poincare] When simplification has been interrupted, escape the end of 
simplification. Otherwise we can be stuck in infinite loop.

This fixes the following bug: when simplifying an expression as
'bigRational1^x*bigRational2^x', we use the rule a^x*b^x --> (a¨b)^x. However,
in this case, a*b can't be reduce (resulting rational would be too big) and
we're stuck in the loop a^x*b^x --> (a¨b)^x --> a^x*b^x --> (a¨b)^x...

remove beautifying x^(p/q) -> root(x,q)^p. This triggered precision

855cec527f [poincare] Power: remove rule i^(p/q) -> e^(i*Pi*p/2q). 
This is handles in ComplexCartesian class when the simplification target
is the user and it doesn't need to be handled for other simplification
targets (we even prefer the first form).
