Plot summary

Plot Summary under every plot should be rendered dynamically based on the values in the plot.
Main characteristics of each plot:

• Time series:
  • long term trend
  • periodically recurring long term changes
  • total deficit volume from given time range
  • seasonality -> dividing to: stacionary/non-stacionary/periodic/non-periodic time series
  • moving average -> based on the selected period of data?
  • autocorrelation
• M-day:
  • numerical description of quantiles
  • numerical differences beteween observation periods
• Flow duration:
  • numerical description of quantiles ?
• Seasonal:
  • median, mode, quantiles, variance, standard deviation, symmetry...
• Pardé:
  • min vs. max

This part should be in output section, because need of work with reactive function (Reactive_Qd) that is defined below the actual plot summary section.
