Added example dataset (avacha) with observed and modelled daily water discharge measurements in cubic meters per second (#6).
Bug fixes
nse with na_rm = TRUE flag and missing values present in both simulated and observed time series now returns the same results as hydroGOF::NSE(). Previously, it did not skip missing values in the observed time series.
Miscellaneous
Introduced parameter testing via quickcheck (#3). Estimated metrics are now validated against their implementations in the hydroGOF package.
