Document Parameters in Tile.py, TileSet.py

I was trying to use these to crop and found it difficult to understand what was going on without reading all the source code.

Additional point of confusion: it would be awesome if TileSet (via delegation to Tile, perhaps) could have a read and write methods, instead of going through an external Reader class.

Ideally I'd like to be able to read the TileSet, manipulate it, and then dump it to disk. I struggled to accomplish this without writing janky new code.

This should be like 3-5 lines of code, no?

The generate_partition_document + write to file could be simplified probably.

Yes to cropping, no to documentation, which probably should be a bit more verbose.
