Convert redundant class fields to local variables

If all local usages of a field are preceded by assignments to that field, the field can be removed, and its usages can be replaced with local variables.

Before :

class Test{

private String myField = "value";


void printMyField(){
  System.out.println(myField);
}



// myField is not used in any other place within this class and it is private

}

After

class Test{

 void printMyField(){
  String myField = "value";
  System.out.println(myField);
}


}

No implementation file, test, or entry point is named. Start by reading the linked ReSharper guidance and Stack Overflow discussion, then locate the static-analysis recipe that handles private fields. Done means fields whose local usages are all preceded by assignments are replaced with local variables without changing behavior.
