"""
A simple dialog that can prompt for values for any arbitrary set of name/value
pairs, where the fields are defined by a list of info passed to the
constructor. A dictionary of initial values can also be passed. Each item in
the fields list is a tuple of 3 items, which are:
* a string to be used for the attribute name for storing the value
* a string to be used for the label
* None, or a dictionary of kwargs to be passed to the wx.TextCtrl ctor
