=head1 NAME

Moose::Meta::Method::Augmented - A Moose Method metaclass for augmented methods

=head1 DESCRIPTION

This class implements method augmenting logic for the L<Moose> C<augment> keyword.

This involves setting up C<inner> for the superclass body, and dispatching to
the superclass from the normal body.

The subclass definition (the augmentation itself) will be invoked explicitly
using the C<inner> keyword from the parent class's method definition.
