In ddiv: Data Driven I-v Feature Extraction

#' Outdoor Time Series I-V Curve Data from SDLE SunFarm.
#'
#' This dataset comes from a long term time-series I-V curves dataset of full sized modules traced by ESL-Solar 500. Data acquired include outdoor time-series I-V curve data taken every 5 minutes from 2013-12-29 09:00:00 to 2013-12-29 13:55:00.
#' This data set is an example of how to use I-V data for a timeseries. The first column is timestamp(tmst) and the second column is I-V curve data(ivdf) that can be separated into voltage(V) and current(I).
