Version 2045 was commited by steve on 2011-10-03 16:03:57 +0100 (Mon, 03 Oct 2011) 

Merge the index-memory branch.

-Vastly improves the memory usage when creating and index.
-If the index creation fails then the index output file is not
 written.

Requires less than half the amount of memory than the old code, and
it is quicker too as a nice side effect.
