#8 property documentation, node shapes, node location

[Nick]

I really like your project. I believe it is currently the only
project that reads gxl and displays it using an applet.
That's an awesome capability!

I am currently working on a software tool that reads
binary data from a simulation and then generates gxl
files that represent communication networks. I want to
use your tool to be able to browse the network.

Here are some things I would like to see to be able to
use your software more effectively.

1) I would like to see some documentation on how to
use property file (.prop).

2) I would like to be able to specify node locations for
drawing specific shapes by reading the gxl x,y,z
position data and draw the graph accordingly.

3) I would like to specify shapes for the nodes and fill
them with color.

Keep up the great work!
