Echo JS 0.11.0

Definitely more advanced than the block based nested gantt chart system I build around later 2000 that had to support NN4.0-6.x and IE4-5 at the time.  It's like flashbacks of the v4 browser wars... I'm traumatized, I can admit it.  Anyone that complains about how hard JS/Browser dev is today doesn't understand the pain... get off my lawn!
