[Ann] xaLib - library to extract data from an array.

Well, it's only a case of "I expect ..." so we shouldn't trust my 
intuition until we've benchmarked it a bit :-)

Having said that - we will still be using script to iterate over the 
keys/elements of the array, so there is likely to be some cost there - 
even before we allow sqlite to index some columns.

I've just started looking at it from the performance point of view, and 
reduced the time for the simple case in the included test stack by 95% 
so it doesn't feel so bad now .... but I'll need to completely rewrite 
the main functions/handlers :-(

I'll try to import the data into an sqlite DB and compare against that 
too - will report with some numbers tomorrow (and come up with a more 
reasonable test case.
