''' Adds @expfolder nodes that represent folders in the file system.

The double-click-icon-box command on an @expfolder node reads the files in
the directory at the path specified and creates child nodes for each file
in the subfolder. Subdirectories are made into child @expfolder nodes so
the tree can be easily traversed. If files have extensions specified in the
expfolder.ini file they are made into @text nodes so the content of the
files can be easily loaded into leo and edited. Double clicking a second
time will delete all child nodes and refresh the directory listing. If
there are any changed @text nodes contained inside you will be prompted
about saving them.

The textextensions field on the expfolder Properties page contains a list of
extensions which will be made into @text nodes, separated by spaces.

For the @text and @expfolder nodes to interact correctly, the textnode plugin
must load before the expfolder plugin. This can be set using the Plugin
Manager's Plugin Load Order pane.
