0.005 => 0.006

Huge number of changes:

- object orientification of code

- threading, implicit and explicit

- Thread.pm, mapping utility functions

- now we require PDL 1.02

- PDLs cannot for the moment be created (sorry about the
  step backwards)

- some more documentation

- demo.pl

0.004 => 0.005

Make it possible to create PDLs on the fly

0.003 => 0.004

Added $P(...) and $TSD(...) syntax for the fortran interface
as well as the ability to specify which types to genericize to
using the TYPES:BSU directive.

0.002 => 0.003

Nothing, made a mistake in uploading to PAUSE.

0.001 => 0.002

Added possibility of having second argument as a semicolon-separated
string.

data a(var,var) should work now with accesses
$a(var0=>foo,var1=>bar)

"Rest" indices now work with "...". "..." is converted to "_DOTS_".

Different datatypes and type coercion: a rudimentary implementation.

PDL::PP now writes also the .pm file automatically.
