#' All-in-one wrapper for the conversion between (R) Markdown, FreeMind mind map, R code, directory structure, and HTML widget.
#' @details \code{mm()} converts between (R) Markdown syntax text, R code, FreeMind mind map code, and directory, and display them in a HTML widget. It is a wrapper for other conversion functions in this package.
#'
#' @param from Character. The source text of the (R) Markdown syntax text, the R code, the FreeMind mind map code, or the path to the directory.
#' @param input_type Character. The type of the input text. It can be \code{'auto', 'markdown', 'mindmap', 'R', 'dir'}. The default value is \code{'auto'}, which means the type will be automatically assgined according to the features of the input text.
#' @param output_type Character. The type of the output. It can be \code{'widget', 'mindmap', 'markdown', 'R', 'dir'}. The default value is \code{'widget'}.
#' @param root Character. The string displayed as the root (center) of the mind map.
#' @param md_list Logical. whether to process lists like headings in the Markdown input.
#' @param md_eq Logical. Whether to include LaTeX equations in the Markdown input when converted to other formats.
#' @param md_braces Logical. Whether to remove \href{https://bookdown.org/yihui/bookdown/cross-references.html}{{#ID}} in the headings of the markdown file (usually in a \href{https://github.com/rstudio/bookdown}{bookdown}> project.
#' @param md_bookdown Logical. Whether the R Markdown syntax text is in bookdown style, i.e. \code{# (PART), # (APPENDIX)}, and \code{# References} as an upper level of the Level 1 heading.
#' @param md_maxlevel Integer or ''. The maximum level of the markdown headings that are displayed in the mind map.
#' @param r_seclabel Character. The ending characters indicating sections in R Markdown.
#' @param r_chunkheading Logical. Whether process the chunk label as headings.
#' @param dir_files Logical. Whether to include files. If \code{FALSE}, only folders are included. If \code{TRUE}, folders and files are included.
#' @param dir_all Logical. Whether to include all files in a directory. If \code{FALSE}, only the names of visible files are included (following Unix-style visibility, that is files whose name does not start with a dot). If \code{TRUE}, all file names will be included.
#' @param dir_excluded Character. The directories which are not included in the output.
#' @param dir_to Character. The path of the output directory.
#' @param dir_quiet Logical. Whether to display the results of generated directories.
#' @param widget_name Character. The name of the html widget.
#' @param widget_width Numeric. The width of the widget.
#' @param widget_height Numeric. The height of the widget.
#' @param widget_elementId Character. The ID of teh Widget.
#' @param widget_options List. Options for the markmap widget. It should be a list passed from the \code{markmapOption()} function.
#'
#' @return Desired output.
