# NAME
# filemgmt.tcl -- file used for manipulation with files
# FUNCTION
# This module is used for all file manipulations. In this file
# a file is read, a new file opened or existing file saved.
# NOTES
# variables:
#
# currentFile
# relative or absolute path to the current configuration file
#
# fileTypes
# types that will be displayed when opening new file
#
# procedures used for loading and storing the configuration file:
#
# newFile
# - creates an empty project
#
# openFile
# - loads configuration from currentFile
#
# saveFile {selectedFile}
# - saves current configuration to a file named selectedFile
# unless the file name is an empty string
#
# fileOpenStartUp
# - opens the file named as command line argument
#
# fileNewDialogBox
# - opens message box to optionally save the changes
#
# fileOpenDialogBox
# - opens dialog box for selecting a file to open
#
# fileSaveDialogBox
# - opens dialog box for saving a file under new name if there is no
# current file
