CppClass adds ": public" to class even though no parent is defined

[grarup]

I'm trying to generate a struct with out a parent and is getting the following result. the ": public" should not be there. Besides it looks a little strange with a extra newline between all variables.

python

        test_class = CppClass(name="test", is_struct=True)
        test_class.add_variable(CppVariable(name="foo", type="int"))
        test_class.add_variable(CppVariable(name="bar", type="int"))

result

	struct test  : public 
	{
		
		int foo;
		
		int bar;
		
	};

env
