#
# PURPOSE:
# To have a command line flash card tool with minimal code, plain text input and output
#
# VISION:
# The goal i have for this script is a basic level emulation of ANKI to where i have a way to
# keep track of a score for each item in each selected deck so that it can pick from a selection
# of the lowest scoring items and shuf them to the user for reenforcement of active recall.

# DEPENDENCIES:
# fzf - https://github.com/junegunn/fzf
# bat - https://github.com/sharkdp/bat
