* File: Plankton.java		Name: Plankton
* This applet/application is designed to graphically represent 
* caches.  It should allow users to load a network, save the network, and 
* create nodes and links to a network that is already there.
*
*	Allow user to load a network
*	Allow user to save a network if in standalone
*	Allow user to create, remove, and  change the location of nodes and 
*             links that have already be created
*
*	As a applet it will need a data_address parameter.
