Added scripts to generate test DB.

scripts/create-dev.sql

+DROP TABLE IF EXISTS items;
+
+CREATE TABLE items (
+    ref INTEGER PRIMARY KEY,
+    name TEXT NOT NULL,
+    price REAL NOT NULL,
+    subscriberPrice REAL NOT NULL
+);
+
+INSERT INTO items (ref, name, price, subscriberPrice)
+    VALUES (1, "Jus d'orange", 1.00, 0.50),
+           (2, "Coca-Cola",    1.50, 1.00);

scripts/generate-dev.sh

+#!/bin/sh 
+
+sqlite3 dev.db '.read ./scripts/create-dev.sql'
