=head1 DESCRIPTION
This class is a subclass from B<Class::Gomor>. It implements objects as hash references, and inherits methods from B<Class::Gomor>.
=head1 GLOBAL VARIABLE
See B<Class::Gomor>.
=head1 METHODS
=over 4
=item B<new> (hash)
Object constructor. This is where user passed attributes (hash argument) are checked against valid attributes (gathered by B<cgGetAttributes> method). Valid attributes are those that exists (doh!), and have not an undef value. The default is to check this, you can avoid it by setting B<$NoCheck> global variable (see perldoc B<Class::Gomor>).
=item B<cgBuildIndices>
This method does nothing. It only exists to make it more easy to switch between B<Class::Gomor::Array> and B<Class::Gomor::Hash>.
=item B<cgBuildAccessorsScalar> (array ref)
=item B<cgBuildAccessorsArray> (array ref)
See B<Class::Gomor>.
=item B<cgGetIndice> (scalar)
This method does nearly nothing. It only returns the passed-in scalar parameter (so the syntax is the same as in B<Class::Gomor::Array>). It only exists to make it more easy to switch between B<Class::Gomor::Array> and B<Class::Gomor::Hash>.
=item B<cgClone> [ (scalar) ]
You can clone one of your objects by calling this method. An optional parameter may be used to create multiple clones. Cloning will occure only on the first level attributes, that is, if you have attributes containing other objects, they will not be cloned.
=item B<cgFullClone> [ (scalar) ]
This method is the same as B<cgClone>, but will clone all attributes recursively, but only if they are subclassed from B<Class::Gomor>. So, objects created with other modules than B<Class::Gomor::Array> or B<Class::Gomor::Hash> will not be cloned.
Another thing to note, there is no catch for cycling references (when you link two objects with each others). You have been warned.
=item B<cgDumper>
Will return a string as with B<Data::Dumper> Dumper method. This is less useful for hashref objects, because they already include attributes names.
