=head1 NAME

Moose::Object - The base object for Moose

=head1 DESCRIPTION

This serves as the base object for all Moose classes. Every 
effort will be made to ensure that all classes which C<use Moose> 
will inherit from this class. It provides a default constructor 
and destructor, which run all the BUILD and DEMOLISH methods in 
the class tree.

You don't actually I<need> to inherit from this in order to 
use Moose though. It is just here to make life easier.

=head1 METHODS

=over 4

=item B<meta>

This will return the metaclass associated with the given class.

=item B<new>

This will create a new instance and call C<BUILDALL>.

=item B<BUILDALL>

This will call every C<BUILD> method in the inheritance hierarchy, 
and pass it a hash-ref of the the C<%params> passed to C<new>.

=item B<DEMOLISHALL>

This will call every C<DEMOLISH> method in the inheritance hierarchy.

=item B<does ($role_name)>

This will check if the invocant's class C<does> a given C<$role_name>. 
This is similar to C<isa> for object, but it checks the roles instead.

=item B<dump ($maxdepth)>

Cmon, how many times have you written the following code while debugging:

 use Data::Dumper; 
 warn Dumper $obj;

It can get seriously annoying, so why not just use this.
