These is a placeholder for the (signed off) patches from [bugs:1250] by Luis. There is also an extra patch that simply formats the class to make it more readable.
The branch is at https://github.com/gilleain/cdk/tree/eqclarom.
Egon, could you pull the signed patch on the equivalent class partitioner please.
I'm okay with the reformatting but I believe it complicates git blame and so I'll let Egon decide.
Applied and pushed.
