New Revision: 23802

URL: http://svn.gna.org/viewcvs/relax?rev=23802&view=rev
Log:
Made special ei, si, mi, and oi numpy structure array.

This is for rapid speed-up of numpy array creation in target function.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion 
models for Clustered analysis.
