Rename in RSTreeMapLayout >> prepareShapesForLayout: inRectangle:

[NSUSpray]

I started gradually reviewing the TreeMap package. It seems to me that some points can be made clearer. Here is my first suggestion:

rename the method

RSTreeMapLayout >> prepareShapesForLayout: shapes inRectangle: rec

to

RSTreeMapLayout >> normalizeAreaOf: shapes byAreaOf: rec

Perhaps the time for refactoring hasn’t come yet and I’m running ahead.
