#' net_index
#'
#' Calculate the Net Effective Temperature (NET) incorporating ambient temperature in degC , wind speed (m/s), and relative humidity (%). It is used in  hot and cold situations.
#'
#' @param t numeric Air temperature in degC.
#' @param rh numeric Relative humidity in percentage.
#' @param wind numeric Windspeed in meters per second.
#' @return Net Effective Temperature
