=item $node->input($string);

Text string to be processed by the node.

=item $text=$node->output();

Output generated after the node has been processed and run

=item $node->process();

Parsing and examination of the node input, completed before it is 
actually run.

=item $node->run();

Process external commands using data from the node object.

=item $node->info();

Returns information on the data within the node

=item $node->tree();

Returns the $tree object that created the node.

=item $node->index();

Returns the tree index pointer for the node.

=item $node->class();

Returns the lest segment of the Perl class for the node.  For example, if 
the actual class is "Text::UberText::Node::Command:, "Command" is returned.
