#24: generate cuts "normal" and at new solution

 Hi,

 I would like to have Bonmin (or Cbc) call my cut generator at both normal
 iterations and when a new solution is found.
 Unfortunately, when I add my cut generator to
 {{{BabSetupBase::cutGenerators()}}} and set
 {{{BabSetupBase::CuttingMethod::atSolution}}} to true, then at
 {{{BonCbc.cpp::152}}}, my cutgenerator is added to Cbc with the options
 normal=false and atSolution=true.
 However, I would need my cut generator to be added with the options
 normal=true and atSolution=true.

 Maybe this can be changed somehow? One way would be to add an extra
 boolean normal to {{{BabSetupBase::CuttingMethod}}} which could be set by
 the user.

 Best,
 Stefan
