preventSmallBoxes
Flag determining if small boxes should be enlarged to ensure some visible area (YES) or not (NO). The default value is NO.
@property (nonatomic, assign) BOOL preventSmallBoxesDiscussion
Sometimes for the trees with a huge difference in weights across children, some boxes may appear too small.
For example, if you create a tree with two nodes weighted 99.9 and 0.1, then the first one will be very large, and
the second one will barely be visible. This maigh look ugly. To prevent this, you can set this flag to YES and
tune the minimalSizeApproximation property to achieve nicer results.

minimalSizeApproximation
Approximation for the minimal allowed size for the boxes. The dedfault value is 10.
@property (nonatomic, assign) float minimalSizeApproximationDiscussion
This property has effect is preventSmallBoxes is set to YES only.
This is only the approximation of the size in pixels, it is NOT an exact value.
“Size” means linear dimension of the box, e.g. width and height.
