super crude and disgusting hackery to get Graphite to work with OpenTSDB, at least my fork anyway. It uses the tree call to display timeseries and TSUIDs to create the actual graphs. There are still many issues to fix such as the fact that TSDB will return data with gaps, and need to calculate intervals, probably normalize data, that kind of stuff. But it's a start. I'll probably move to the 10 branch and refactor all storage/path related calls into their own classes since Graphite could be made to work with other systems.
