# ABSTRACT: Source for a HASH of ARRAYs

#pod =pod
#pod
#pod =head1 SYNOPSIS
#pod
#pod   # The basic data structure
#pod   my $deps = {
#pod       foo => [ 'bar', 'baz' ],
#pod       bar => [],
#pod       baz => [ 'bar' ],
#pod       };
#pod
#pod   # Create the source from it
#pod   my $Source = Algorithm::Dependency::Source::HoA->new( $deps );
#pod
#pod =head1 DESCRIPTION
#pod
#pod C implements a
#pod L where the items names are provided
#pod in the most simple form, a reference to a C of C references.
#pod
#pod =head1 METHODS
#pod
#pod This documents the methods differing from the ordinary
#pod L methods.

#pod =pod

#pod =head2 new $filename
#pod
#pod When constructing a new C object, an
#pod argument should be provided of a reference to a HASH of ARRAY references,
#pod containing the names of other HASH elements.
#pod
#pod Returns the object, or C if the structure is not correct.
