example schema now stores most field values

[Michael Sokolov]

While upgrading from 4.2.1 to 4.6.1 I noticed that many of the fields 
defined in the example schema.xml that used to be indexed and not stored 
are now defined as indexed and stored.  Is there anything behind this 
change other than the idea that it would be more convenient to have all 
the values available?  Is it somehow cheaper to recover them from the 
index now, so that storing (ints, say) is free?
