v1.74.0

-- Move updateVersions and supporting function out of Utils/submodules to Utils/Shared in DataTree standalone mode to update repo versions.
-- Move JSON library from Utils to Utils/Shared for use in DataTree standalone mode to write JSON files when expoerting proc stream.

* DataTree, v1.8.0

-- Fix issue of DataTree in standalone mode not getting the right value for config parameter "Export Processing Stream Functions".
-- Remove reliance on static method TreeNodeClass.ExportProcStreamFunctions to get value of config parameter which tells you if code should export processing stream. Instead switch to getting the value directly from the ConfigFileClass global variable cfg which is automatically updated when changes are made to any config parameters through the configSettingsGUI.

* Utils, v1.3.0

-- Add JSON library so that export of procesaswing stream to JSON files can work in DataTree in standalone mode.
-- Add repoManagement/updateVersions.m and supporting function so that use can use the script to update versions in DataTree in standalone mode.
-- When saving config parameters in configSettingsGUI update global ConfigFileClass variable cfg so that DataTree in standalone mode has immediate access to changes in config params without having to rerun dataTree.
