+ *
+ * Rules we follow are from PSR-2 as well as the rectified PSR-2 guide.
+ *
+ * - https://github.com/FriendsOfPHP/PHP-CS-Fixer
+ * - https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md
+ * - https://github.com/php-fig-rectified/fig-rectified-standards/blob/master/PSR-2-R-coding-style-guide-additions.md
+ *
+ * If something isn't addressed in either of those, some other common community rules are
+ * used that might not be addressed explicitly in PSR-2 in order to improve code quality
+ * (so that devs don't need to comment on them in Code Reviews).
+ *
+ * For instance: removing trailing white space, removing extra line breaks where
+ * they're not needed (back to back, beginning or end of function/class, etc.),
+ * adding trailing commas in the last line of an array, etc.
