# PURPOSE : This file contains a namespace called TolProject with its
#           functions. It's for managing TOL projects that are groups of TOL
#           objects (text files, table files, etc.). They are showed as a 
#           hierarchical treeview.

#
# PURPOSE: The purpose of this namespace is organize code and functions and
#          manage common options for all tol project editors such as last
#          edited files, last directory used, etc.
#          A special namespace is created for each instance of project.
#
# VARIABLES:
#   options -> common options for all project windows:
#     wm,state  -> initial window project state
#     geometry  -> initial window project geometry
#     lastDir   -> last directory used
#     chEdited  -> boolen for saving last project files path
#     numEdited -> number of last project files path to save
#     edited    -> path of last used projects
#   tmpOpt      -> temporary array used to store the widgets and variables of
#              the options dialog.
#   num_Project -> incrementally number to identify each project window
#   typelist    -> list of type files supported by project editor
#   defExt      -> default extension for files managed by project editor
#   num         -> incrementally number to identify each item in the 
#                 [Included TOL Files] section of project file
