6de497c2ed [apps/shared] Templatize FloatParameterController to handle float/double 
parameters.

Fix bug: when entering "e^234" as a parameter of a model keeping floats,
the FloatParameterController would accept the number (because e^234 is
defined in double) and store an undefined value in the model (because
e^234 is undefined in float).

83fda9a587 [apps/proba] Fix Chi Square computations 
Because the values can be very small or very big, computations should
not be made sequentially, to prevent rounding errors.
For instace, for degrees of freedom = 70, coefficient() would return 0
event though the cumulativeDistributiveFunctionAtAbscissa was not 0.

7ec6bea991 [apps/proba] More seamless computation 
If the user computes P(x<a) which gives b, then presses OK on b, return
a.
This prevents some comutation errors such as for student distribution
with 0.05 degrees of freedom, P(x<9900000) then press ok on the result
