ac6f23684d [poincare] Clean Expression and Layout builders 
Before: Opposite(Opposite(Rational(1))) misleadingly created the
expression "-1"; now, Opposite::Builder(Opposite::Builder(Rational(1)))
creates "--1"

c6039423a9 [poincare] When simplifying an expression, also compute the approximation from the reduced 
expression to avoid loss of precision.

If an expression is reduced to a ComplexCartesian(a, b), we compute the
approximation from ComplexCartesian(a,b) instead of going through the
potentially complicated expression resulting from beautifying
(sqrt(a^2+b^2)*exp(i*(arctan(b/a) -Pi/2*sign(b)) for example)

94603b2b7d [poincare] Layout::serialize is serializeForParsing or ParsedExpression 
serializeForParsing serializes the layout once,
serializeParsedExpression serializes the layout, parses it and
serializes it again.

61b1b8a09d [poincare] Add Expression::FunctionHelper class 
That class is meant to contain data about named functions (e.g. sin,
tan...) in one place: their name, their number of children and a pointer to
a builder. The derived class corresponding to each such function
contains a private instance (m_functionHelper) and a getter.
The previous parser is removed, along with unecessary
constructors (used by the previous parsers).
