Started working on visualizing HDD events
Added visualization of HDD events and tooltips
Big refactor of the web visualization.  Now it'll be super easy to add advanced features
Changed font of main viz labels and fixed orientation of labels
Added tooltip for the lanes to show thread/process info, and removed some unnecessary info that was cluttering the event tooltips
Use shortname on overview.  Fixed tooltip orientations
Hide play button on regular graph viz for now
Maximum size for overview now 150px
Added window resize and fixed up everything so that resize works nicely
Small brush modification to prevent UI glitches
Small bugfix; ie disallows modifications like this to bboxes
Small bugfix repeated; ie disallows modifications like this to bboxes
added TraceRunnable for wrapping and XTraceSpanTrace class for basic spans on top of events with start events and marker end events
Added some tests for XTrace options, to make sure that they are (a) propagated (b) serialized and (c) deserialized correctly.  Oh look, the tests fail.  Fixed the existing bugs in option propagation (incorrectly deserializing lengths as signed ints rather than unsigned).  Added a few convenience methods to XTraceContext to access the options of the currently-set metadata
Fixed up some of the options implementation
Removed unnecessary numOptions from report
Let's not be so hasty in printing stack traces willy nilly when we can't connect to the X-Trace server
Partial commit of some critical path viz for demo
Updated the JSON for the upload and download examples
For some reason, was adding an extra blank bar unnecessarily.  Fixed
