[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).
