Delete function FindGoodLimits. Use services of THLimitsFinder in TTreePlayer::SetEstimate.
Delete function FindGoodLimits.
Use services of THLimitsFinder in TTreePlayer::SetEstimate.

Modify DrawSelect to use the modified function TTreeFormula::SetAxis.
This new function takes care of setting the bit kIsInteger in the axis.
This also fixes a problem when histograming integer variables. The number of bins
was not correctly recomputed.

Add a fix from Philippe in MakeClass to initialize members holding object pointers.
