# == Synopsis
# This module encapsulates the application's config hash by adding
# default, load, and save methods.  Also behaves as a global hash,
# meaning you can access it from anywhere in your code like:
#   AppConfig[:images_dir]
# or
#   AppConfig['images_dir']
# Note this is because the implementation is a Mash instead of
# a Hash and does cause a limitation where the key must be either
# a symbol or a string.
