h02: Lab05 with pass-by-reference

The goal of the homework is to change initCoord and initBox to use pass-by-reference (see Lec 10 notes) instead of pointers. We recommend doing this homework first before tackling the lab, since this will allow you to focus on implementing the logic and functionality of the Lab05, without getting lost on the syntax. Note: there is no need for *b or *coord or -> when passing the struct by reference.

Create a new repo called hw02_<username>. Make sure the repo is PRIVATE.

Use the same starter files as for Lab05.
