[SCIP] How could I access the new constraints created by SCIPbranchVar() ?

[myroslav]

I guess I need to access constraints corresponding to the variable's 
bounds and then use SCIPgetDualsolVarbound() method to get the dual 
value  but I could not figure out how to get constraints corresponding 
to the variable's bounds.

Sincerely,

Myroslav
