New Revision: 15504

Log:
The model-free constraint matrix A is now of numpy.int8 type.

The values of this matrix should be negative, zero, or positive integers for 
model-free analyses,
so the type has been changed.  When using the example at
https://mail.gna.org/public/relax-users/2012-03/msg00037.html (Message-id:
<CAED9pY_Z1wGEg3gZo3WCkhvYTBdqs-Feex5Og4vJFovgJkUOyw@xxxxxxxxxxxxxx>), the 
virtual memory usage
during Monte Carlo simulations drops from 648 to 641 Mb.  This should also 
increase the scaling
efficiency on clusters.
