Folder graphmaker

graphmaker is a simple, partly implemented
example of a java applet to draw graphs,
where a Graph consists of nodes and edges.

Each node has an x,y pixel location.

Each edge connects two nodes.

All of the work to figure out and respond
to the user's gesture is contained in a
class called GraphGesture.  This is the
class that will need to throw exceptions
if the user does something that the program
cannot respond to properly.

Then the main applet class GraphMaker should
catch those exceptions, and then display a
proper warning message on the applet window.
