In tvmComp: Discounting and Compounding Calculations for Various Scenarios

#'Calculates Present Value of a Single Cash Flow that is Compounded Continuously.
#'@details
#'According to \insertCite{tman;textual}{tvmComp}, a continuously compounding scenario is that where the time intervals between interest payments are infinitely small.
#'The Method \code{pvContinuousCompSingleCF()} was developed for this scenario and calculates Present Value of a Single Cash Flow that is Compounded Continuously. The method gives Present Value when values are passed to its three arguments. Here \code{r} is annual rate, \code{n} is number of years and \code{fv} is Future Value
#'@param r A number.
#'@param n A number.
#'@param fv A number.
#'@return Input values to three arguments \code{r} , \code{n} and \code{fv}.
