+ * TS Configs... I hate them.
+ *
+ * TS Configs can point to other configs in two way:
+ *
+ * - `extends`, which is a "super" config that you need to fall back on.
+ *      An important note about "super" configs, is that the paths are relative
+ *      to the folder that the "super" config is in. OR the baseUrl.
+ * - `references`, which lets you provide an array of TS Configs or directories
+ *      that include TS Configs.
+ *      These configs have different file includes and excludes.
