MyCPAN::Indexer::Coordinator - Provide a way for the various components to communicate

	my $componentA   = MyCPAN::Indexer::ComponentA->new;
	my $componentB   = MyCPAN::Indexer::ComponentB->new;

	my $coordinator = MyCPAN::Indexer::Coordinator->new;

	# each component gets a reference
	$componentA->set_coordinator( $coordinator );
	$componentB->set_coordinator( $coordinator );

	# the coordinator knows about all of the components
	$coordinator->set_component( 'A', $componentA );
	$coordinator->set_component( 'B', $componentB );

	$componentA->set_note( 'cat', 'Buster' );

	my $cat = $componentB->get_note( 'cat' );

	# Any component can find any other component
	$componentB->get_coordinator->get_component( 'A' )->method_in_A;

The coordinator keeps track of the components in MyCPAN::Indexer. It acts as a central point where all comunication can flow so everything can talk to everything with only 2N connections.

It automatically sets up a notes object to act as a scratchpad. Every component can read from and write to the notes object.

new

Create a new Coordinator object.

get_component( NAME )

Retrieve the component named NAME.

set_component( NAME, REFERENCE )

Set the component with name NAME to REFERENCE. So far there are no restrictions on reference, but it should be a subclass of MyCPAN::Indexer::Component or at least something that acts like that class.

As a convenience, these methods dispatch to the notes object:

	get_note
	set_note
	get_config
	set_config
	increment_note
	decrement_note
	push_onto_note
	unshift_onto_note
	get_note_list_element
	set_note_unless_defined
