[Pdx-pm] Converting a monolithic program to mvc

[benh]

As Jeff and I found out last night you can create 'globals' (see
below), it's not the cleanest thing that I've ever done but it works.

package one;
use two;

$main::globalvar = { hello => 'Phred' };

my $two = two->new;

package two;
print 'Hello ', $main::globalvar->{hello};
