new version of contrib-intarray

Mark,

we prepared new version of contrib-intarray -
index support for 1-D integer arrays using GiST.

Changes:

- Improved regression test
- Current implementation provides index support for one-dimensional
array of int4's - gist__int_ops, suitable for small and medium size
of arrays, and gist__intbig_ops for indexing large arrays
(we use superimposed signature with length of 4096 bits to represent sets,
see Sven Helmer,1997).

Regards,
Oleg
