[Geysers] Geyser statistics and graphs updated

[Ralph Taylor]

I have posted the analysis of the downloads in the Upper Geyser Basin for 15
July and the Lower Geyser Basin for 13 July downloads.  Sorry, I ran out of
time and did not process Grotto, Pyramid, or Spouter, and I have not
completed the analysis of Mercury or Narcissus data from last winter.

I will be away until 1 August, so no downloads until 5 August.  I'll try to
get the missing data from the last downloads posted soon.
