Added code to handle the annual_flow graph separate from the daily_flow.
The annual_flow is plotted using the barcharts so I created a new
function, createFlowPlot.js.
Merge branch 'master' of github.com:USGS-CIDA/nar_ui into NAWQAAN-384
Fix for the bug where min flow is zero. If the min flow is zero, we will
now use the normal scale and formatting rather than the log scale.
Took out unneeded code from the flow duration plot. Now retrieving TN
discrete data rather than TKN for the hydrograph/flow duration plots.
