Hello World

I am considering using Fluidiom in my research but there is quite a 
bit of customization I need to make to the current code. I have been 
trying to get a simple HelloWorld example to work where I create a 
cube and set down a plane but the code seems to be fairly coupled. I 
figured I would then play around this getting the intervals to flex.

I have the cube but I am unable to get the Floor to show up. Any ideas?

Two files are included:
MyFabricFactory.java & HellowWorld.java

MyFabicFactory just builds a fabric object consisting of 8 verticies 
and 12 elastics.

Oh, one more thing, when I was running this, why did only two of the 
verticies have "balls" for the joints?
