docs: def add_frontmatter(file_name, title, makenew=False):
      """
      Adds basic frontmatter to a MarkDown file that will be used in a Jekyll project.
  
      Parameters
      ==========
      file_name : String
          Relative file path from where this method is called to the location of the file that will have frontmatter added.
      title : String
          Title of the page that will go into the Jekyll project.
      makenew : Boolean (OPTIONAL)
          If set to True, will create a new file with the frontmatter next to the original file with "_added_frontmatter" appended to its name. Otherwise, the method simply edits the original file.
  
      Examples
      ========
      Suppose we have the following directory:
      data/
          doc.md
      
      To write to a new file doc_add_frontmatter.md and add frontmatter:
      >>> from aide_document import jekyll
      >>> jekyll.add_frontmatter('doc.md', 'Document', True)
  
      The last parameter can be omitted if you want to just overwrite doc.md.
