Re: Cluster membership in SPSS

[Alan Mead]

Attached is a patch to 0.8.5 quick-cluster.c to support the
/PRINT=CLUSTER subcommand that identifies the cluster membership of each
case in the analysis.  I also included test syntax, data, and output.

John has suggested some stylistic changes that are included in this
patch, but three last three suggestions are not in this patch:

In addition, I've been looking over the regression.c code to see how it
implements /SAVE but I'm not sure I can replicate it in the cluster code.
