=head1 NAME
Data::Hive::PathPacker - a thing that converts paths to strings and then back
=head1 VERSION
version 1.008
=head1 DESCRIPTION
Data::Hive::PathPacker classes are used by some L<Data::Hive::Store> classes to convert hive paths to strings so that deep hives can be stored in flat storage.
Path packers must implement two methods:
=head1 METHODS
=head2 pack_path
my $str = $packer->pack_path( \@path );
This method is passed an arrayref of path parts and returns a string to be used
as a key in flat storage for the path.
=head2 unpack_path
my $path_arrayref = $packer->unpack_path( $str );
This method is passed a string and returns an arrayref of path parts
represented by the string.
