Rough draft of a monthly hydro plot.

Took another approach to this one, wrapping it in a class.
Seems good so far. Might try auto-scaling?
add some command line args to jsoncpp test file for easier testing.
Dynamic re-scale function seems to be working but not being called in the right spot.
Auto expanding x axis working ok...

improve notes for matplotlib on fedora.
change to absolute path for temp json files. (and add comment)
some plots are now sin functions - approx one cycle per year
