-/* Example usage
-
-This sample program makes a new struct which contains a
-character and a tox_list_t. It then prompts a user for
-input until he enters q or e. It then adds each character
-to the list, and uses a special for loop to print them.
-It then removes all the 'z' characters, and prints the list
-again.
-
-//Notice that the data to be put in the list *contains* tox_list_t;
-//usually, this is the other way around!
-typedef struct tox_string {
-   char c;
-   tox_list_t tox_lst; //Notice that tox_lst is *NOT* a pointer.
-} tox_string_t;
-
-int main()
-{
-   tox_list_t head;
-   tox_list_new(&head); //initialize head
-
-   //input a new character, until user enters q or e
-   char c = '\0';
-   while (c != 'q' && c != 'e') {
-      scanf("%c", &c);
-      tox_string_t* tmp = malloc(sizeof(tox_string_t));
-      tmp->c = c;
-      tox_list_add(&head, &tmp->tox_lst); //add it to the list
-   }
-
-TOX_LIST_FOR_EACH() takes a struct tox_list and a name for a temporary pointer to use in the loop.
-
-TOX_LIST_GET_VALUE() uses magic to return an instance of a structure that contains tox_list_t.
-You have to give it a temporary tox_string_t, name of tox_list_t member inside our structure (tox_lst),
-and the type of structure to return.
-
-   TOX_LIST_FOR_EACH(head, tmp)
-      printf("%c", TOX_LIST_GET_VALUE(*tmp, tox_lst, tox_string_t).c);
-
-   TOX_LIST_FOR_EACH(head, tmp) {
-      if (TOX_LIST_GET_VALUE(*tmp, tox_lst, tox_string_t).c == 'z') {
-         //If you delete tmp, you have to quit the loop, or it will go on infinitly.
-         //This will be fixed later on.
-         tox_list_remove(tmp);
-         break;
-      }
-   }
-
-   printf("\n");
-   TOX_LIST_FOR_EACH(head, tmp)
-      printf("%c", TOX_LIST_GET_VALUE(*tmp, tox_lst, tox_string_t).c);
