'''A specialized file_chooser function for multiplierz files. Otherwise,
works just like file_chooser.
'parent' is the parent of the dialog--used when this is called by a GUI
element. It is perfectly fine to leave it as None, and the GUI frame will
have no parent.
'title' can be left blank for the following default titles based on mode:
r - 'Choose multiplierz File:'
w - 'Save File:'
m - 'Choose multiplierz Files:'
'mode' is one of 'r', 'w', and 'm', just as for file_chooser.
**kwargs can include any additional options to pass to the FileDialog constructor,
such as defaultDir (default directory).'''
