#' Creates a \code{ggplot2} chart of the population for a CO municipality
#'
#' Takes some basic input on the timeperiod and county then creates a
#' plot of the data in \code{ggplot2}. Similar to the muni_ts_data()
#' function. Can create timeseries from 1990 to 2040 (beyond 2013 are
#' forecasts).
#' Note: Requires dplyr, ggplot2, ggthemes, scales, and grid R packages.
#'
#' @param fips The County FIPS number (without leading Zeros)
#' @param beginyear The first year in the timeseries Defaults to 1990.
#' @param endyear The first year in the timeseries Defaults to 2013.
#' @param base Base font size.
