0ed0cc56e9 [poincare] Remove characteristicXHalfRange 
Method characteristicXHalfRange was used to compute the range on which
to display cartesian function in Graph. With the new zoom algorithm,
this method is deprecated.

a9c94236c2 [poincare] Implemented further derivation methods and updated tests. 
Derivation now works on tangents and the three hyperbolic functions.

5cf85368ea [poincare] Added framework to derivate unary functions, and implemented it for Sine 
Added a method unaryFunctionDifferential to ExpressionNode and Expression, to be implemented by subclasses representing unary functions.
Added a function derivateUnaryFunction to Derivative, to factor (f°g)' -> g' * f'°g.

051e608835 [poincare] Added method didDerivate to Expression and ExpressionNode 
This method is to be implemented by derivable expression subclasses, for use in Derivative::shallowReduce. It performs the calculation for the derivative, and returns whether calculations happened.

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.

94fb5815f9 [poincare] Fix replaceReplaceableSymbols for parametered expressions 
Scenario: ans*int(0,x,0,0)->x then cos(x) crashed because replaceReplaceableSymbols

expression

f6a5759a16 [poincare] Fix the replacement of unknowns in the storage 
In the Graph app, define f(x) = cos(x) and g(x)=diff(f(x),x,x).
The graph and table are perfectly computed, but in the Calculation apps,
g(5) fails.
