Mrshu/tosdr repository

This PR adds the following two commits which should simplify getting the latest data from `tosdr.org`.

-------
update: Added tosdr.org as a submodule

* Added the tosdr.org repository as a submodule to simplify dumping the
  training data.

* Made sure that the text is always on one line.

----------

update: Use a file from /points as an example …

* Instead of `example.json` which was not present in the
  tosdr.org/points directory this commit uses any-time-with-notice.json
  which can be found in the repository.

-----


As a side note, the tosdr.org repository can be initiated by running  `git submodule init` and then `git submodule update` will get the latest data.
