Decide on initial workspace

[willzeng]

We need to decide what will show up when a user loads a graphdoc for the first time (assuming they are not linked directly to a workspace).

Options:

• Load whatever their most recent workspace (will need cookies or user system)
• Load the most recently added nodes/connections (say 20 of them)
• Load the "hottest" nodes/connections by some metric
• Allow users to star a node so that it appears on initial load (this would overlap with the save workspace capability)

I'm leaning towards some hottest calculation if they have never opened it before and otherwise to show what they last looked at, unless they directly load a particular workspace.

Thoughts @davidfurlong and @vpontis ?

Show top 20 most connected nodes and most recently edited 20 nodes.

This is leaving the milestone since we will by default only support sharing workspaces, sharing a gdoc without a workspace selected is deprecated.
