+ * This function takes a C-string and allocates a temporary string ID.
+ * The StringID of the bound string is valid until BindCString is called
+ * another NUM_BOUND_STRINGS times. So be careful when using it.
+ *
+ * @note formatting a DATE_TINY calls BindCString twice, thus reduces the
+ *       amount of 'user' bound strings by 2.
+ * @todo rewrite the BindCString system to make the limit flexible and
+ *       non-round-robin. For example by using smart pointers that free
+ *       the allocated StringID when they go out-of-scope/are freed.
