#' @title Method launchApp
#'
#' @description  A method which launches Shiny application of the SangerContig
#'  and SangerAlignment instance.
#'
#' @param object A SangerContig or SangerAlignment S4 instance.
#' @param outputDir The output directory of the saved new SangerContig or SangerAlignment S4 instance.
#' @param colors A vector for users to set the colors of (A, T, C, G, else). 
#'   There are three options for users to choose from. 
#'     1. "default":  (green, blue, black, red, purple). 
#'     2. "cb_friendly":  ((0, 0, 0), (199, 199, 199), (0, 114, 178), (213, 94, 0), (204, 121, 167)). 
#'     3. Users can set their own colors with a vector with five elements.
#'
#' @return A \code{SangerContig} or \code{SangerAlignment} object.

#' @title Method writeFasta
#'
#' @description  A method which writes FASTA files of the SangerRead,
#'  SangerContig, and SangerAlignment instance.
#'
#' @param object A SangerRead, SangerContig, or SangerAlignment S4 instance.
#' @param outputDir The output directory of generated FASTA files.
#' @param compress Like for the \code{save} function in base R, must be \code{TRUE} or \code{FALSE} (the default), or a single string specifying whether writing to the file is to use compression. The only type of compression supported at the moment is "gzip". This parameter will be passed to \code{writeXStringSet} function in Biostrings package.
#' @param compression_level This parameter will be passed to \code{writeXStringSet} function in Biostrings package.
#' @param selection This parameter will be passed to \code{writeFastaSC} or \code{writeFastaSA}.
#'
#' @return A \code{SangerRead}, \code{SangerContig}, or \code{SangerAlignment} object.
