rainfall works -- need to redo diagnostics
removed diagnostics from graph.print, making schedule.print.  all diagnostics will be in other functions
testing diagnostics -- not perfect yet
moved diagnostics from exp.trts to diagnostic.plot
checking that the first two functions work.
added some labels to the top of the sched.  now says "day.1" instead of simply "1"
have updated the diagnostics for param.result and water.amt
rewrote treatments.over.time.pdf
modified function that produces precip.time
