Remove file documentation

These will not be used in the Sphinx documentation, and most were
self-explanatory and only there to make the Doxygen index look nice anyway.
Where there was actually useful information, it has been preserved as regular
comments.

-   The program draws a bunch of rectangles with borders, using instancing.

-   This is not particularly realistic or optimal, but serves as a decent rough

-   about 100000 rectangles.
