Show HN: Terminal-Based Flashcards in Bash

Mostly a proof of concept based on fla.sh[1].

Proposed changes are :

## minimalist interface I wanted the quiz to show up in the middle of an otherwise empty screen, kind of like with what is done in the so called "distraction free" editors.

## only two results per quiz For various reasons I don't like the typical 5 possible notations (hard, difficult, normal, mild and easy or something like that). So only two possibilities : either you know the answer, or you didn't. So only two keys to press : enter or space.

## A different spaced-repetition algorithm. The most ambitious parts. I want to experiment using softmax and a somewhat complicated (but easily customizable) scoring system that would be entirely based on the activity log. Very much a work in progress, so far.
