#' Convert Degrees to Radians and Vice Versa
#'
#' @description Base R doesn't have a native function to change degrees to but
#'   requires radians for trig functions. These are to help handle that.
#'
#' @param deg Input degree you want to change to radians.
#' @param rad Input radian you want to change to degrees.
