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"

ecf3f2ea0f [poincare] Create a a flag on Expression that is set when the 
approximation encouters a complex value

All approximation methods take the complex format into account.

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).

1a8c6b6ae9 [poincare, escher, ion, apps] Split the huge umbrella header poincare.h, to reduce build time. 
This should be a NFC, but surprisingly, it also reduces size... so what does it change ?
