For example Class c was changed to Class _class
and Constructors[] cc was changed to _constructors etc.
The name change is _followed by the proper name
This make it way easier to read the code rather than my initial lettered variables

For testing I added a test for a simple class with no recursion to see if method and field are in the output
since I already did Super class and Interface I just checked method and Field to make sure the refactoring didn't change anything
