' Function to extract all files from a compressed "folder"

' All files and folders will be extracted from the ZIP file.
' A progress bar will be displayed, and the user will be
' prompted to confirm file overwrites if necessary.
' This function can also be used to copy "normal" folders,
' if a progress bar and confirmation dialog(s) are required:
' just use a folder path for the "myZipFile" argument.
' myZipFile [string] the (path and) file name of the ZIP file
' myTargetDir [string] the path of the (existing) destination folder
