Task:

Implement the function int Singer::changeme(std::string name,int age,int hits) :
This function should check if the values passed by name, age and hits are different than those stored. And if this is the case it should change the values. This should be done by calling:

If name_ is to be changed by calling the set_name() function with name as argument
If age_ is to be changed the set_age() with age as argument
If hits_ is to be changed by directly assigning the value of hits to hits_.
