# File: DualIndexHashObject.pm
|
|
# Author: pragma_
|
|
#
|
|
# Purpose: Provides a hash-table object with an abstracted API that includes
|
|
# setting and deleting values, saving to and loading from files, etc. This
|
|
# extends the HashObject with an additional index key. Provides case-insensitive
|
|
# access to both index keys, while preserving original case when displaying the
|
|
# keys.
