Fix bug 3608123 -- Diab's topdl bug
Update VERSION to 2.006 for release in readme's
Make gnuplot and prima demos in list match perldl ones
Minor tweaks to some INSTALL/READMEs
Finished Release_Notes for PDL-2.006
Add a default Index.pod for online browsing
Update permissions on new Index.pod
Remove unix-only double check for gnuplot

The Gnuplot_demo.pm was failing due to a unix-only
test for the gnuplot executable.  Removed that code
and added a bit more downsampling for the last set
of 3d images for speed.
Add a more informative message to Gnuplot demo if PDL:Graphics::Gnuplot is missing.
Make sure placeholder Index.pod does not get installed

Since it was being installed first, the scantree.pl script
failed because it couldn't open the destination location.
Remove read only Index.pod so scantree.pl works
Update VERSION to 2.006_01 for new development
Fix rcols with colsep and $PDL::undefval

Missing fields in the middle were being returned
as the empty string '' rather than undef which happened
if they were at the end.  Now mapping them uniformly
to undef.  This is sf.net bug #3608928
Fix %hash randomization bugs in PDL tests

It appears that t/hdr.t and t/niceslice.t tests
had hash comparison checks assuming (%h1) and (%h2)
if the two hashes were equal.  This should fix
