Are we allowed to define maximum recursion for raycolor?

[Leuxll]

In the original main.cpp, we have num_recursive_calls set to 0, the output of my images doesn't have any reflection at all. But when I changed the num_recursive_calls to 5 the reflections are showing. Does that mean we can just set a constant num_recursive_calls?

num_recursive_calls = 0

num_recursive_calls = 5

num_recursive_calls is the current depth of the recursion. Use a separate hardcoded variable for max_num_recursive_calls. You can hardcode it to 10.
