"""
Modifying slide rule:

The customization feature is intended to handle most cases where you require
a specialized slide or stator. But if you would like to add a new slide to
the toolbar, you need to make changes in three places:

1. In constants.py (this file) you need to add new entries to SLIDE_TABLE,
STATOR_TABLE, SLIDE_DICTIONARY, STATOR_DICTIONARY, and DEFINITIONS so that the
slides appear in the toolbars.

2. In genslides.py, you need to add new class objects to generate the
graphics associated with your slide and stator.

3. In window.py, you need to import the new class objects from #2.
