Biodiverse::Spatial::compare sub should recognise recycled results

[GoogleCodeExporter]

The spatial (moving window) analyses recognise when the results are
constant across a neighbour set, and recycle the results into each element
in that set.  This results in smaller file sizes, as the results are stored
once and each element then just refers to this.   

However, the compare sub (as used in the randomisations) does not recognise
this.  It therefore stores a different set of of results for each element,
even though these are identical for the neighbour set.  For large data sets
this can result in proportionally larger file sizes.

If the spatial conditions and definition queries for the base and comp data
sets are identical, and recyclable, then the comparison should also recycle
the results.
