distinct colors

Hi!

Just to let you know. I have slightly improved the normalizer. You can now send #distinctColorUsing: aBlockOrSymbol

Consider the following example:

b := RTMondrian new.

b shape circle.

b nodes: Collection withAllSubclasses.

b edges connectFrom: #superclass.

b layout tree.

b normalizer

normalizeSize: #numberOfMethods;

distinctColorUsing: #package.

b

This gives to each class a color depending on its package. 

Cheers,

Alexandre
