[webservices] SeisGramWeb: browser-based seismogram viewer using IRIS ws-timeseries

[Robert Casey]

	Hi Anthony-

	Thanks for the update, I see that your updated app is at the same URL  
as your sample trace example below.  I was able to figure out how to  
do the two-tap zoom.  Looks great!  Where do you think you'll take  
things from here?

	-Rob
