Bug: Node size failed to recover to original size if it was clicked on the info panel.

GEXF viewer with Sigma.js

version 0.1
Resources used:
Sigma.js, bootstrap

Extension from sigma.js:
1. Show attributes when mouse over
2. Use AJAX/Php/Jquery to list available gexf files on server, populate file selections.
3. When file selection changes, remove all the nodes and edges in sigInst, create a new sigInst. This is not the right way, but it works so far.
4. Add separation force between different groups of node. Separation force adjustable, 0: none, 1: full.

To Do:
1. make it take full screen.
2. select which attributes to show.						Done
3. apply separation force to a specific attributes, rather than just the group id.
4. add separation within a cluster.
5. Do clustering in browser, using clusterfck, worker
6. FB login in browser, pull data real time, show nodes real time

gexf files goes to data folder.
It takes whole window now, with information panel on the right.
When a node is selected, the connected nodes are listed on the info-panel.
When mouse hover over a name on the info-panel, the corresponding node in the graph lit up.
