layout
public boolean layout(Point offset, Word word, Rectangle cloudArea, CloudMatrix mainTree)
Tries to position the given word in the given area. First a start point is chosen, then theRectTree
of the word and the main area is used to detect whether the word can be placed at the given position, or not. If not, the current point is moved slightly in a spiral manner, similar to the approach of Wordle.
