Recursively splitting children tiles

[adl1995]

@tboch - You mentioned in the Google docs:

You can recursively call the children method on a HipsTile instance to split tiles as needed, as long as the tile width is >1.

However, I'm not sure which tile should be split. When the children method is called it returns four HipsTile. Should I iteratively split each of these four children until their width is greater than 1?

@adl1995 - Please put that question of whether to split tiles recursively or not on the list of things to discuss in the telcon this afternoon.
