=head1 NAME
Math::Symbolic::Custom::Base - Base class for tree tests and transformations
=head1 SYNOPSIS
  # Extending the Math::Symbolic::Custom class:
  package Math::Symbolic::Custom::MyTransformations;
  use Math::Symbolic::Custom::Base;
  BEGIN {*import = \&Math::Symbolic::Custom::Base::aggregate_import}
   
  our $Aggregate_Export = [qw/apply_transformation1 .../];
  sub apply_transformation1 {
     # ...
  }
=head1 DESCRIPTION
This is a base class for your extensions to the Math::Symbolic::Custom
class.
To extend the class, just use the following template for your custom class:
  package Math::Symbolic::Custom::MyTransformations;
  use Math::Symbolic::Custom::Base;
  BEGIN {*import = \&Math::Symbolic::Custom::Base::aggregate_import}
   
  our $Aggregate_Export = [...]; # exported subroutines listed here.
   
  # Now implement the subroutines.
  # Exported subroutine names must start with 'apply_', 'mod_',
  # 'is_', 'test_', 'contains_', or 'to_'
   
  # ...
   
  1;
=head2 EXPORT
Uses a custom exporter implementation to export certain routines from the
invoking namespace to the Math::Symbolic::Custom namespace.
But... Nevermind.
=head1 SUBROUTINES
=cut
package Math::Symbolic::Custom::Base;
use 5.006;
use strict;
use warnings;
our $VERSION = '0.613';
our $AUTOLOAD;
=head2 aggregate_import
aggregate_import() is the only public subroutine defined by
Math::Symbolic::Custom::Base and should only be called in BEGIN blocks like
the one shown in the SYNOPSIS above.
=cut
sub aggregate_import {
    my $class = shift;
    no strict 'refs';
    my $subs = ${"${class}::Aggregate_Export"};
    foreach my $sub (@$subs) {
        *{"Math::Symbolic::Custom::$sub"} = \&{"$class\:\:$sub"};
    }
}
1;
__END__
