Data::StackedMap is a Perl object that stores key/value pairs in a stacked fashion.

SYNOPSIS

 use Data::StackedMap;
 
 my $data = Data::StackedMap->new();

 $data->set("foo" => 10);
 print $data->get("foo"); # prints '10'

 $data->push();
 print $data->get("foo"); # still prints '10'
 
 $data->set("foo" => 20);
 print $data->get("foo"); # now prints '20'
 
 $data->pop();
 print $data->get("foo"); # prints '10' again

This class implements a simple key/value map where each key can exist multiple times in different layers in a stack.
